Steps to reproduce

I'm not sure what's triggering it unfortunately.

Expected Behavior

No response

Actual Behavior

Ever since v1.18.2681.0, I've been getting this issue every day. I never notice when it actually appears, but eventually I notice a ghostly 'Close' button hovering on my Desktop, and it appears to be something attached to Windows Terminal. In the taskbar, I can see it's attached to Windows Terminal and it has the title Pop-upHost. If I try to select it, I get a WindowsTerminal.exe is not responding, and closing it closes my Windows Terminal.

Windows Terminal appears to work fine if I just leave it alone though.

Taskbar:

WT_Taskbar_Pop-upHost

Button over desktop:

Ghostly_Close

Using NirSoft GUIPropView to inspect two different Pop-upHost handles (red sections redacted):

GUIPropView_Pop-upHost_1

GUIPropView_Pop-upHost_2

The process (i.e. 13F0) for the second one is Desktop Window Manager (dwm.exe).
