weird bug involving window disappearing after being left on pause for a while when going back from fullscreen after playing it again

[wadbr]

Describe the bug sorry for the weird title, it is a weird bug 😆 so if you leave a video for a long time, then play it again and enter fullscreen and go out of fullscreen (using double click or enter) the video becomes blank, the window becomes unclickable (hotkeys still work), audio still works, the window title dissapears from the taskbar and even windows task manager. the only way to close it is through Process Hacker.

To Reproduce Steps to reproduce the behavior:

1. Open a video
2. leave it for a long time (12h+, mostly days, between hibernations and sleep cycles for the pc)
3. play it again
4. go into full screen
5. come out of full screen
6. bug starts here
7. can't do anything to the window itself but audio will still work and hotkeys will still work only if you dont click on anything else
8. if you click on anything else the window will disappear, process will hide from task manager

Expected behavior for the window to not disappear and the video to still be working

Screenshots If i try to take a screenshot the window disappears so no idea... I'll try to take a photo of my screen with my phone next time it happens.

Additional context I am using a 2 gpu setup, 1 gpu to run a screen, the problem usually occurs on the main monitor with the external AMD gpu (i never tried it on the 2nd monitor with the internal gpu),

This is probably a very very longshot since it's so weird, but I'm prepared to do additional steps required to gather additional data/debug info.

Windows 10, 64bit, one monitor is 1080x1980 and the secondary is 1360x768
