Managed to reproduce this bug on Windows 10.0.22631. Attached below is a video of the bug occuring.

Observations:

1. You need to resize the window to be larger, then smaller again for this issue to occur.
2. The bug does not occur if the resizing amount is too large.
3. It also occurs when you resize the window vertically.
4. One cannot record nor take a photo of the bug from the same computer.

I'll try fixing this bug.

Thanks for filing! This looks similar to #14865. Does the corruption go away when you move the window /?
