Hello,

(I hope this is a right place to place my question.)

When I play a CS:GO (game) on a full screen and some kind of pop-up appear (for example volume change or notification), screen completely freezes and I can't do anything except mouse moving.
Even ctrl + alt + f1 is not working. Only thing which works is kernel sys requests shortcuts so I have to reboot every time.

This problem also occurs with other games or programs on full screen but I couldn't replicate it every time, maybe 70% of times it freezes.
(mentioned CS:GO is running on nvidia and desktop is running on intel UHD when freeze happens)

Does someone have got similar problem? Can someone please suggest fix?
Thanks.
