+# VwDrawRootBuffered Buffering Fix
+
+## Problem
+The VwDrawRootBuffered class had a critical bug in its GDI resource management that caused:
+1. **Resource leaks**: The new bitmap created for double buffering was never deleted
+2. **Visual artifacts**: The old bitmap handle was deleted instead of being properly restored
+3. **Incorrect cleanup**: The destructor was left cleaning up a DC with a corrupted bitmap state
+
+## Root Cause
+The bug was in the bitmap selection and cleanup code:
+
+```cpp
+// WRONG - Old buggy code:
+HBITMAP hbmpOld = AfGdi::SelectObjectBitmap(m_hdcMem, hbmp);
+fSuccess = AfGdi::DeleteObjectBitmap(hbmpOld);  // BUG: Deleting the OLD bitmap!
+Assert(fSuccess);
+// ... draw and blit ...
+// BUG: Never cleanup the NEW bitmap (hbmp)
+```
+
+When `SelectObjectBitmap` is called, it:
+1. Selects the new bitmap (`hbmp`) into the DC
+2. Returns the **old** bitmap that was previously in the DC (typically a stock 1x1 monochrome bitmap)
+
+The bug was deleting this old bitmap immediately, which is wrong because:
+- Stock GDI objects shouldn't be deleted (may cause issues)
+- The new bitmap (`hbmp`) was never deleted, causing a resource leak
+- The DC was left with no valid bitmap to restore to
+
+## Solution
+
+### DrawTheRoot (with ReDrawLastDraw support)
+Keeps the bitmap cached in `m_hdcMem` for potential `ReDrawLastDraw` calls:
+
+```cpp
+// Clean up any previous cached bitmap and DC
+if (m_hdcMem)
+{
+    HBITMAP hbmpCached = (HBITMAP)::GetCurrentObject(m_hdcMem, OBJ_BITMAP);
+    if (hbmpCached)
+        AfGdi::DeleteObjectBitmap(hbmpCached);  // Delete the previous cached bitmap
+    AfGdi::DeleteDC(m_hdcMem);
+    m_hdcMem = 0;
+}
+
+// Create new memory DC and bitmap
+m_hdcMem = AfGdi::CreateCompatibleDC(hdc);
+HBITMAP hbmp = AfGdi::CreateCompatibleBitmap(hdc, width, height);
+HBITMAP hbmpOld = AfGdi::SelectObjectBitmap(m_hdcMem, hbmp);
+// Don't delete hbmpOld - it's the stock bitmap from the new DC
+
+// ... draw to m_hdcMem ...
+
+// Blit to screen (bitmap stays in m_hdcMem for ReDrawLastDraw)
+::BitBlt(hdc, ..., m_hdcMem, ...);
+```
+
+### DrawTheRootRotated (local resources)
+Uses local DC/bitmap since rotation makes caching impractical:
+
+```cpp
+// Create local memory DC and bitmap
+HDC hdcMem = AfGdi::CreateCompatibleDC(hdc);
+HBITMAP hbmp = AfGdi::CreateCompatibleBitmap(hdc, width, height);
+HBITMAP hbmpOld = AfGdi::SelectObjectBitmap(hdcMem, hbmp);
+// Don't delete hbmpOld - it's the stock bitmap from the new DC
+
+// ... draw to hdcMem ...
+
+// Blit rotated to screen
+::PlgBlt(hdc, ..., hdcMem, ...);
+
+// Clean up local resources
+AfGdi::SelectObjectBitmap(hdcMem, hbmpOld, AfGdi::OLD); // Restore stock bitmap
+AfGdi::DeleteObjectBitmap(hbmp);  // Delete our custom bitmap
+AfGdi::DeleteDC(hdcMem);
+```
+
+### DrawTheRootAt (already correct)
+This method already had the correct pattern - it was used as a reference for the fix.
+
+## Key Points
+
+1. **Stock bitmap handling**: When a new DC is created, it comes with a default 1x1 stock bitmap. When we select our custom bitmap, the stock bitmap is returned but we **do not** delete it. Stock GDI objects should not be deleted by applications. Instead:
+   - For cached DCs (`DrawTheRoot`): Leave the custom bitmap selected; it will be deleted on next draw or in destructor
+   - For local DCs (`DrawTheRootRotated`, `DrawTheRootAt`): Restore the stock bitmap before deleting the DC
+
+2. **Resource ownership**: 
+   - `DrawTheRoot`: Keeps the custom bitmap selected in `m_hdcMem` for caching
+   - `DrawTheRootRotated`: Uses local DC, restores stock bitmap, deletes custom bitmap and DC
+   - `DrawTheRootAt`: Uses local DC, restores stock bitmap, deletes custom bitmap and DC
+
+3. **Exception safety**: Added proper cleanup in catch blocks for `DrawTheRootRotated` to prevent leaks on exceptions. The stock bitmap is restored and the custom bitmap is deleted before rethrowing.
+
+4. **ReDrawLastDraw**: This optimization re-blits the cached bitmap when the form is disabled, avoiding a full redraw. It requires `m_hdcMem` to be persistent with a valid custom bitmap selected.
+
+## Testing
+The fix should be tested by:
+1. Running FieldWorks applications and checking for visual artifacts during text rendering
+2. Monitoring GDI object counts to ensure no resource leaks
+3. Testing the disabled form scenario (which uses ReDrawLastDraw)
+4. Testing rotated views if any exist in the application

+# VwDrawRootBuffered Buffering Implementation Summary
+
+## Overview
+Successfully re-implemented the buffering code in VwDrawRootBuffered to fix critical GDI resource management bugs that were causing resource leaks and visual artifacts.
+
+## Changes Made
+
+### Files Modified
+1. **Src/views/VwRootBox.cpp**
+   - Fixed `VwDrawRootBuffered::DrawTheRoot` method
+   - Fixed `VwDrawRootBuffered::DrawTheRootRotated` method
+   - Destructor was already correct
+
+### Key Fixes
+
+#### 1. DrawTheRoot (Lines 4869-4990)
+**Purpose**: Main drawing method with bitmap caching for ReDrawLastDraw optimization
+
+**Changes**:
+- Added proper cleanup of previous cached bitmap before creating new one
+- Correctly manage stock GDI bitmap (don't delete it)
+- Keep custom bitmap selected in m_hdcMem for caching
+- Custom bitmap gets deleted on next draw or in destructor
+
+**Before** (Buggy):
+```cpp
+// BUG: Deleted old bitmap immediately, leaked new bitmap
+HBITMAP hbmpOld = AfGdi::SelectObjectBitmap(m_hdcMem, hbmp);
+fSuccess = AfGdi::DeleteObjectBitmap(hbmpOld);  // WRONG!
+```
+
+**After** (Fixed):
+```cpp
+// Proper cleanup of previous cached bitmap
+if (m_hdcMem) {
+    HBITMAP hbmpCached = (HBITMAP)::GetCurrentObject(m_hdcMem, OBJ_BITMAP);
+    if (hbmpCached)
+        AfGdi::DeleteObjectBitmap(hbmpCached);  // Delete previous bitmap
+    AfGdi::DeleteDC(m_hdcMem);
+}
+
+// Create new DC and bitmap
+m_hdcMem = AfGdi::CreateCompatibleDC(hdc);
+HBITMAP hbmp = AfGdi::CreateCompatibleBitmap(hdc, width, height);
+HBITMAP hbmpOld = AfGdi::SelectObjectBitmap(m_hdcMem, hbmp);
+// Don't delete hbmpOld - it's a stock GDI object
+// Custom bitmap stays in m_hdcMem for caching
+```
+
+#### 2. DrawTheRootRotated (Lines 4992-5086)
+**Purpose**: Rotated view drawing (90° clockwise)
+
+**Changes**:
+- Use local DC and bitmap (rotation makes caching impractical)
+- Properly restore stock bitmap before cleanup
+- Delete custom bitmap
+- Added exception path cleanup
+
+**Before** (Buggy):
+```cpp
+// BUG: Same issues as DrawTheRoot
+HBITMAP hbmpOld = AfGdi::SelectObjectBitmap(m_hdcMem, hbmp);
+fSuccess = AfGdi::DeleteObjectBitmap(hbmpOld);  // WRONG!
+// No cleanup of hbmp
+```
+
+**After** (Fixed):
+```cpp
+// Create local DC and bitmap
+HDC hdcMem = AfGdi::CreateCompatibleDC(hdc);
+HBITMAP hbmp = AfGdi::CreateCompatibleBitmap(hdc, width, height);
+HBITMAP hbmpOld = AfGdi::SelectObjectBitmap(hdcMem, hbmp);
+// Don't delete hbmpOld
+
+// ... draw ...
+
+// Proper cleanup
+AfGdi::SelectObjectBitmap(hdcMem, hbmpOld, AfGdi::OLD);  // Restore stock bitmap
+AfGdi::DeleteObjectBitmap(hbmp);  // Delete custom bitmap
+AfGdi::DeleteDC(hdcMem);
+```
+
+### Documentation Added
+1. **BUFFERING_FIX.md** - Detailed explanation of the bug and fix
+2. **IMPLEMENTATION_SUMMARY.md** - This file
+
+## Root Cause Analysis
+
+### The Bug
+The original code had two critical issues:
+
+1. **Immediate deletion of stock bitmap**: After selecting a custom bitmap into a DC, the code immediately deleted the stock bitmap that was returned. Stock GDI objects should never be deleted by applications.
+
+2. **Resource leak**: The custom bitmap was never deleted, causing a GDI resource leak.
+
+### Why It Failed
+- Windows `CreateCompatibleDC` creates a DC with a default 1x1 monochrome stock bitmap
+- `SelectObjectBitmap` selects the new bitmap and returns the previous one (the stock bitmap)
+- The buggy code deleted this stock bitmap, corrupting the DC state
+- The custom bitmap was never cleaned up, causing leaks
+- This led to visual artifacts and eventual GDI resource exhaustion
+
+## Testing Strategy
+
+### Manual Testing (Requires Windows)
+1. **Visual Artifacts**: Run FieldWorks applications and observe text rendering
+   - Look for flickering, tearing, or incomplete draws
+   - Test scrolling and window resizing
+   - Test with different font sizes and writing systems
+
+2. **GDI Resource Monitoring**: Use Task Manager or Process Explorer
+   - Monitor GDI Objects count for the application
+   - Should remain stable during extended use
+   - Should not increase continuously during normal operations
+
+3. **ReDrawLastDraw**: Test disabled form scenario
+   - Open a form with text
+   - Disable the parent form (e.g., show a modal dialog)
+   - Verify text remains visible and correct
+
+4. **Rotated Views**: If the application uses rotated text views
+   - Verify rendering is correct
+   - Check for resource leaks
+
+### Automated Testing
+The existing test infrastructure (TestVwRootBox.h) doesn't specifically test VwDrawRootBuffered. Consider adding:
+- Unit tests for DrawTheRoot with mock IVwRootBox
+- GDI object count tracking tests
+- Exception safety tests
+
+## Build Requirements
+- Windows with Visual Studio 2022
+- Desktop Development workloads
+- The fix requires no changes to build configuration
+- Cannot be built in Linux environment
+
+## Architecture Decisions
+
+### Why Two Different Patterns?
+
+**DrawTheRoot - Cached DC**:
+- Keeps bitmap in m_hdcMem for ReDrawLastDraw optimization
+- Avoids recreating bitmap for every disabled-form redraw
+- Used by SimpleRootSite.cs when form is disabled
+
+**DrawTheRootRotated - Local DC**:
+- Uses local resources because rotation complicates caching
+- Simpler resource management
+- Proper cleanup on every call
+
+### Why Not Delete Stock Bitmaps?
+- Stock GDI objects are system-managed
+- Deleting them can cause undefined behavior
+- `DeleteObject` will fail for stock objects (return FALSE)
+- Debug builds would hit assertions on failure
+- Best practice is to never delete stock objects
+
+## Related Code
+
+### C++ Implementation
+- `Src/views/VwRootBox.cpp` - VwDrawRootBuffered class
+- `Src/views/VwRootBox.h` - Class declaration
+- `Src/AppCore/AfGfx.cpp` - GDI wrapper functions
+
+### C# Implementation
+- `Src/ManagedVwDrawRootBuffered/VwDrawRootBuffered.cs` - Managed version
+  - Already had correct resource management using IDisposable pattern
+  - Used as reference for understanding correct behavior
+
+### Usage
+- `Src/Common/SimpleRootSite/SimpleRootSite.cs` - Uses ReDrawLastDraw
+- All text rendering in FieldWorks applications
+
+## Performance Considerations
+
+### Before Fix
+- GDI resource leak over time
+- Potential for resource exhaustion
+- Visual artifacts degrading user experience
+- Possible crashes when GDI handles exhausted
+
+### After Fix
+- No resource leaks
+- Stable GDI object count
+- Clean visual rendering
+- ReDrawLastDraw optimization maintained
+
+## Compatibility
+- No breaking changes to public APIs
+- No changes to behavior from caller's perspective
+- Only internal resource management improved
+- Compatible with existing usage patterns
+
+## Future Improvements
+1. Add automated tests for VwDrawRootBuffered
+2. Consider implementing IDisposable pattern for more explicit resource management
+3. Evaluate if ReDrawLastDraw optimization is still needed (managed version doesn't implement it)
+4. Consider adding GDI object tracking in debug builds
