NVidia X Server widnow doesn't show me perfomance or any other mode
us flag

after couple of months I wanted to play a game of CSGO on my laptop dual booting windows and linux. I haven't been using Win10 ever since I've switched to linux in January and I used to play CSGO on performance mode easily before. But now, maybe due to some driver update I can't see all options in nvidia x server settings like before. Bellow is the look of my nvidia x server window. Thanks in advance!

Applications in fullscreen mode overlaps any other window

Kubuntu 21.04. For example, if I put my web browser in full-screen with F11 I cannot show any other window in front of the fullscreen app. It's like the fullscreen app doesn't detect where is the focus.

Ubuntu hangs due to Xorg process

I am using Ubuntu 20.04. Once in a fortnight or so, the system hangs, and the system fan goes to full speed at the same time. After that, no keyboard or mouse input works, not even Ctrl+Alt+F3 to switch to a command line console. So there is no way for me to monitor if any background process is malfunctioning. The only choice I have is to use the power button to reboot.
