I get these errors when using fullscreen mode / F11. Every time I switch to/from fullscreen the whole monitor becomes black for a few seconds. When using fullscreen the screen is skewed and the color is a bit white, but both don't show on a screen recording with OBS. When trying to take a screenshot with Windows+Shift+S the black screen appears again and Minecraft is minimized. https://youtu.be/vcXF4oE4OYw this is the recording. Windows fullscreen works perfectly.

It seems some resolutions work better than others. This one worked okay on my 1440x900 primary (very old) monitor after switching to another app and back (still black screen though). The white and stretching seemed to be gone or at least less noticeable and I could take this screenshot with Windows+Shift+S. Still errors in the logs though

I also encountered other glitches like the mouse clicking on the wrong items and not getting out of fullscreen (even with the settings) anymore.

Might be worth opening another issue for this but heres another problem in fullscreen.

When i have 2 monitors connected, the game will show on both with one being the actual game and the other being a frozen frame
