Issue:
When I go full screen be it in youtube, video player or even just a screenshot app then my screen goes blank for 5 or so seconds.
This happens whether using nouveau or when in nvidia (by blacklisting nouveau in grub).
Since this does not happen in Windows or other linux distro (previously used kubuntu), it shouldnt be hardware related.
SOLVED:
Apparently disabling Adapative Sync (VRR) in KDE Settings fixed it!
