No, it affects any/all applications. From memory it has occurred with Kate,
Firefox, VLC, MPV, Dolphin. Not that I play games for any significant amount of
time (maybe avg 1 hour/day)they have not been affected as yet. In m

If you disable compositing (hit Alt+Shift+F12), does the problem stop
happening?

I have Alt+Shift+F12 on both machines and will wait to see if it happens again
though bear in mind it may be many days.

Just some additional information which may or may not be of assistance, both
the affected PCs are never turned off though the dual boot machine is restarted
into Windows every day. The unusual thing which causes no harm is

Does Alt+Shift+F12 cause the time widget to display incorrect time? Both
machines are displaying 4.31 p but when I go to change the time (right click >
adjust time and date) the time is correct, approx 8.34pm.The widget tim

That problem is Bug 353983 which was fixed in version 450.57 of the proprietary
NVIDIA driver. You might consider updating it.

Experienced a freeze on one PC last night at approx 9:33pm. The preceding post
is an excerpt of the kernel and syslog surrounding that time. The crash
occurred while watching mpv which I killed and I then resumed the movie

Just a thought, as the time displayed in the clock widget was correct, 9:33,
does that indicate that Alt+Shift+F12 had been overidden by mpv which as a
video player might invoke a compositor?

Not necessarily; the nvidia panel freeze isn't a 100% thing.

The CPU usage issue I last raised is likely an associated issue but may not be
present when the active window freezes as seen in subsequent freezes. I think I
have found a commonality with both machines: In, I think all ca

I did some more tests on large files and discovered that there is indeed some
problem with Kubuntu that is directly affected by what size file it is working
on. For the tests I used MKVtoolnix GUI Ver 50 once on Kubuntu 20
