Windows Terminal version

Current main

Windows build number

10.0.19045.4291

Other Software

No response

Steps to reproduce

  • Set Direct3D backend active. All rendering backends are affected.
  • Run tab with any profile.
  • Zoom-in by Ctrl+Wheel until it crashes.
    • Direct3D: ~ One minute of scrolling for my HW setup.
    • Direct2D: ~10 minutes of "doing nothing" with same result (crash).

Expected Behavior

Reasonable zoom limits. E.g.: One text cell should not exceed the size of the terminal window.

Actual Behavior

Direct3D:

What do you mean with "doing nothing"?

I mean I scrolled (Ctrl+Wheel) intensively with the mouse for 10 minutes and did nothing else 😅

AtlasEngine: Improve robustness against weird font sizes (#17258)
f62d2d5 
This clamps the font sizes between 1 and 100. Additionally, it fixes
a warning that I randomly noticed when reproducing the issue: D2D
complained that `EndDraw` must be called before releasing resources.
Finally, this fixes a crash when the terminal size is exactly (1,1)
cells, which happened because the initial (invalid) size was (1,1) too.

This doesn't fully fix all font-size related issues, but that's
currently difficult to achieve, as for instance the swap chain size
isn't actually based on the window size, nay, it's based on the cell
size multiplied by the cell count. So if the cell size is egregiously
large then we get a swap chain size that's larger than the display and
potentially larger than what the GPU supports which results in errors.

Closes #17227
