When waking up after going into sleep mode while the game is running, the game screen can freeze and the window can glitch

I don't believe this i valid. The red color shown in the attached picture is just the default accent color of the UWP Bedrock application. It also appears if you resize the window too quickly.

I mean, stuck on that window

It doesn't seem to depend on whether the window is full screen/maximized.

I don't see how turning off your monitor could have any affect on the game, unless your setup has Windows put the computer to sleep when it detects that the monitor is off. In that case, what you are seeing is a result of the computer waking from sleep. Does that sound accurate?

That makes sense.

I can't seem to reproduce it on my laptop, so this may only be an issue for desktops.

Thank you for your report!
