UWP window fails to fill client area #4068

Describe the bug

UWP window will suddenly fails to fill client area when dragging the window to resize, usually after some extended period of system up time (something like 1 week of not restarting). And when this happens, all UWP window (including system settings) behaves the same. If you drag the window border to enlarge the window, new client area becomes transparent. Note: The app is NOT freezing, and is still interactive (even buttons in the transparent area is clickable if you try)

This issues happens universally, throughout any Windows 10 and 11 versions, and any hardware. (There are intel, amd, and nvidia gpu users reporting this)

WinUI3 window, win32 window and XAML island does not have such issue.

Restarting dwm.exe does NOT fix this issue.

Steps to reproduce the bug

Not sure how to reproduce, just keep the system running for some days. The longer it runs, it happens more likely.
