Description techxgames 2021-12-10 23:22:36 UTC

SUMMARY
Once the video I  got playing stops playing, that's when the display starts going to sleep.  However, it won't restore, or if it does, it takes a while.

STEPS TO REPRODUCE
1. Wait for the display to sleep
2. Try to wake  it up by moving the cursor
3. 

OBSERVED RESULT
This happens whenever I'm watching a video on Firefox.  I would normally notice this after I wake up (from literal sleep).
I can see the cursor moving, but the rest of the display stays black.  I can still open new applications (like Konsole by keyboard shortcut).

When I try to forcefully restore everything by running `kwin --replace`, no applications are restored, like as if it's newly logged in.

EXPECTED RESULT
Everything that was open should show up prior to the display going to sleep.

SOFTWARE/OS VERSIONS
Operating System: KDE neon Unstable Edition
KDE Plasma Version: 5.23.80
KDE Frameworks Version: 5.89.0
Qt Version: 5.15.3
Kernel Version: 5.11.0-41-generic (64-bit)
Graphics Platform: Wayland
Processors: 4 × Intel® Core™ i7-4510U CPU @ 2.00GHz
Memory: 15.5 GiB of RAM
Graphics Processor: Mesa DRI Intel® HD Graphics 4400

ADDITIONAL INFORMATION
I will try to simulate this with a much shorter duration (like leaving it alone for an hour).  Also, the laptop didn't go to sleep.

Comment 1 techxgames 2021-12-11 00:16:51 UTC

So I just tried now, and the inverse is happening: the desktop is restored, but frozen for about a minute or 2.

Comment 2 techxgames 2021-12-11 01:53:54 UTC

Just now, I switched my display to another device, and when I went back to it, Plasma locked up
