labelled not a bug
In many cases after hibernating/waking from sleep, I get a blank screen. In
past kde versions, switching tty session usually solved the issue. For example,
switching back and forth once would lead to screen with artefacts, then
repeating it couple of times restored the display. In the latest version, no
amount of switching helps, since I can only get screen with artefacts, and only
solutions appear to be restarting kwin, or resetting AMD driver, both of which
end the applications running in that session (which is undesirable).
STEPS TO REPRODUCE
1. Hibernate plasma
2. Restart computer
OBSERVED RESULT
The screen is blank. On switching between ttys, screen artefacts appear
(unusable with horizontal banding in entire screen). Resolved by restarting
kwin. Replicable about 50% of times. No particular trigger or cause that I
could identify
EXPECTED RESULT
Everything should be restored as normal
