Update vulkan swapchain recreation examples #3390

RoryO · 2020-08-06T19:18:46Z

Following up on #2626, this PR does a couple things. First, it changes all the Vulkan examples on the timing of resizing the swapchain. Currently the sdl and glfw examples respond to the library window resize events and then trigger the swapchain resize on those events. This accidentally works on Windows as Windows does not repaint a window using a GPU accelerated surface as it's resized. It treats accelerated windows differently as Windows repaints other windows as they're resized. Window managers on Linux and OSX will always resize the window contents as it's resized. This leads to a disconnect in timing where the display system redraws the window with different dimensions before processing the event and resizing the swapchain. This causes a crash with VK_ERROR_OUT_OF_DATE_KHR.

The best thing with Vulkan swapchain resizing is don't trigger recreating the swapchain outside the render loop. Instead, always present the swapchain images and check for VK_ERROR_OUT_OF_DATE. This is the last possible moment in the Vulkan pipeline. If it's out of date, resize the swapchain and go on to the next render loop.

Also made a minor updates. Fixed the clear color reference, the clear_color variable exists and was not copied to the vulkan ClearValue property.

Hello,

I'm not sure I understand how the issue as labelled relates to adding a full precompiled SDL into the repository. I can't accept it into the repo, but I presume the other changes are very worth looking at. Could you force-push this without the unrelated SDL changes?

Thank you!

RoryO · 2020-08-06T19:57:53Z

Sure. Would you consider separate PR updating the SDL build matching the glfw build or should I just leave it out?

…ing set. Broken by a06eb83 (#3390)

ocornut · 2020-08-07T13:25:03Z

I pushed a commit for the clear color issue which got broken by a06eb83. Fix is ede8825 (will conflict with yours which is more verbose).

…#3390, #2626)

ocornut · 2020-08-07T13:43:51Z

Thank you!

I have uploaded a simplified version of that fix here:
https://github.com/ocornut/imgui/compare/features/vulkan_resize_fix
For new code please try to stay within the code style.

The problem is this needs to be merged and reworked for multi-viewport support in the docking branch.
With the separation of rendering and platform back-end it'll require some work and testing.
The "swapbuffer" function of the Vulkan back-ends for owned secondary viewport would need to go via the PlatformIO functions to retrieve the size back from the platform back-end.

Could you figure out the proper suitable fix applicable to docking branch with multi-viewport enabled? Since I presume the current fix won't work for secondary viewports owned by the back-end.

RoryO · 2020-08-15T21:39:06Z

Yep, currently docking head crashes with the glfw vulkan example and resize

Looking at this now since my next work is getting #3372 working with docking.

Sorry, I'm a bit lost on what you want me to do here. Do you want me to cherry pick and merge your commit into this branch and open a separate PR for docking?

Sorry, I'm a bit lost on what you want me to do here. Do you want me to cherry pick and merge your commit into this branch and open a separate PR for docking?

For master, I believe my branch is a simpler replacement to your branch, and could be merged as-is later.

But the issue is the change won't work as-is for docking, so ideally you would:

start from docking, cherry-pick my simplified version of the change
then figure out what it would take to make that same fix work with multi-viewports and make a new PR (I don't think you can force-push into this same PR if the base branch changed?)
when it works I can merge the first commit into master+docking and the other commits you'll produce into docking.

RoryO · 2020-08-17T21:32:10Z

For master, I believe my branch is a simpler replacement to your branch, and could be merged as-is later.

I think yours is fine. Can you go ahead and merge it to master now, and I'll work on the viewports?

ocornut · 2020-08-18T09:03:22Z

I think yours is fine. Can you go ahead and merge it to master now, and I'll work on the viewports?

I'd prefer to first be sure the technique is going to work in a similar manner with multi-viewport. In your branch based from docking you can cherry-pick that commit as a first step, and we merge on both side when ready.

You should be able to call platform_io.Platform_GetWindowSize() to get window size in the renderer back-end.

hinxx · 2020-08-18T13:18:28Z

Tried this PR on my Linux Mint 19.3 system, and I still get the app to crash if window resize is attempted. Happens for both SDL and GLFW with vulkan.

RoryO · 2020-08-18T22:53:05Z

Okay I updated, cherry-picked @ocornut a65a6cae41d172c01d813da310e6b25d4fce5d80 and retargeted to docking.

@hinxx Thank you for trying this out! As of this comment resizing the main window works, resizing any child windows crashes like the above capture. That's what I'm fixing next, hopefully end of today.

(None of the animations are half drawn when viewing locally, seems like the capture utility I use sometimes captures a half drawn frame)

RoryO · 2020-08-19T00:47:14Z

Yeah, it works fully with viewports! I think this is good to go now.

hinxx · 2020-08-20T09:30:49Z

Thanks for the update @RoryO .
I still have the same issue:

hinxx@obzen ~/Code/x11imgui/examples/example_sdl_vulkan $ ./Debug/example_sdl_vulkan 
Xlib:  extension "NV-GLX" missing on display ":0.0".
[vulkan] Error: VkResult = -1000001004
Aborted

The last resize of the 'Demo ImGui Demo' window killed the app because the mouse went out of the main window.

I was also experiencing random crashes of the app with the same error if I tried to move the window around (not resizing it, just moving). Sometimes resizing the ImGui windows inside the main window would cause the crash as well. I did not manage to capture those.

When going outside the main window by resizing the internal window GDB backtrace says:

This is right after the call to vkAcquireNextImageKHR().

When resizing the main window the GDB backtrace is a bit different:

Thread 1 "example_sdl_vul" received signal SIGABRT, Aborted.

Nevertheless, it again happens right after the call to vkAcquireNextImageKHR().

RoryO · 2020-08-20T10:58:54Z

Oh drat I forgot that it's possible that vkAcquireNextImageKHR could also return out of date. That's a rarer case though what @hinxx uses for a window manager trips it immediately. It takes some playing around with the window on KDE and I did reproduce it. It's the same fix, wherever we call vkAcquireNextImageKHR check for out of date, if so rebuild the swapchain and continue on to the next frame. I'll have that up tomorrow.

Changed my mind and merged this today on master, better than nothing (but would of course be good to get the multi-viewport equivalent fixed and tested!). Thanks again.

hinxx · 2020-08-22T19:53:34Z

@RoryO , we're getting there.. not yet there though. This time it took a little longer to get it to crash. It happens only after the internal window is moved out of the main window, and then resized. Resizing the main window does not crash the app anymore.

RoryO · 2020-08-22T23:20:50Z

That one has me concerned. Viewports are rendered in two functions RenderWindow and SwapBuffers. RenderWindow does a render pass and SwapBuffers does the page flip. I'm trying to think through what can potentially happen in the next step, ImGui_ImplVulkan_SwapBuffers if we do the same catch and return in ImGui_ImplVulkan_RenderWindow. We may get out of date again when presenting the image, which is okay and we'll skip this frame, we may get a garbage looking frame drawn, which is ugly and unprofessional, or we may get a validation error I'm not thinking of at the moment which puts us in undefined behavior.

One easy way to solve it is turn SwapBuffers for the default vulkan renderer a no-op and perform the swapchain image presentation at the end of RenderWindow. Another way is keeping them separate and creating a flag, probably within ImGuiViewportDataVulkan, that signals don't perform the page flip because that swapchain image may be garbage data. I'd probably do the former as I can't see a reason for separating the render pass from the queue presentation here. I'll leave it for @ocornut if he has any other insight.

e: Actually from poking around a bit more, setting viewport->DrawData to null and calling viewport->DrawDataP.Clear() in RenderWindow might be the answer.

RoryO · 2020-08-23T23:20:32Z

Okay I went with nulling out the draw data approach. Hopefully that's the last of them.

hinxx · 2020-08-29T06:28:56Z

@RoryO, works fine for me now, no more crashes.

ocornut · 2020-08-29T08:25:52Z

I don't fully understand what's going on, it seems like this is cancelling out some the refactor done and committed in df89a16 so it's dififcult to understand. Would be good to rebase it on latest and then ensure only the strict necessary amount of changes are in the commits (some of the clear color changes were reverted etc.)

…ocornut#3390, ocornut#2626)

ocornut · 2024-05-07T13:59:15Z

I went back to this as #2626 #3390 #3758 #7508 #7513 are all circling around the same problem and this seems like the first solution to it, with ample commentary.

I am forced to harshly divide and conquer to move forward with the amount of task, so any issues/pr with extraneous noise is unfortunately always delayed.

As of today (and it may not have been the case at the time of the PR),

In examples's main.cpp:

the ClearValue related changes are not needed (this was changed already)
the if (g_SwapChainRebuild) continue; are not needed (the only thing coming afterwards is a call to FramePresent() which does the same thing.
so there are no remaining changes in this PR for the main.cpp files.

In backend itself:

Your addition and handling of SwapChainOutOfDate is similar to @InsideBSITheSecond's addition and handling of CanPresent in Vulkan: Fixing secondary viewport resize problems on linux #7513, if not possibly exactly the same. Hopefully the commentary and variants here should clear up some of the question I asked in Vulkan: Fixing secondary viewport resize problems on linux #7513.

I'm NOW going to run over those in details and attempt to merge something. Sorry for the delay!

ocornut · 2024-05-07T14:17:31Z

I have merged the remaining parts of your PR as 8b2c6dd, based on comparing with #7513 I came to the conclusion they did the same thing.

One difference if your PR defer actual call to ImGui_ImplVulkanH_CreateOrResizeWindow to next ImGui_ImplVulkan_RenderWindow() call, while the other PR did the call immediately but set the flag to avoid swapping. They are essentially equivalent but I prefer the approach of calling from a single spot instead of two spots.

I've credited you both.

Given the complexity of this, I would appreciate if everyone affected could confirm that it fixes the situation for them.

Thanks everyone!
