SUMMARY *** 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. Wake from hibernate to get a blank screen (not dependably reproducible. Occurs about half the time with no particular trigger I can identify. 2. Switch tty sessions back and forth (ctrl+alt+F3 followed by ctrl+alt+F2) 3. Repeat multiple times OBSERVED RESULT The tty2 session continues to show screen artefacts (its unusable with horizontal banding in entire screen) EXPECTED RESULT tty2 session showed normal display SOFTWARE/OS VERSIONS Linux Kernel Version: 6.4.6-1-MANJARO (64-bit) AMD driver: amdgpu Mesa version: 23.0.2-2 KDE Frameworks Version: 5.108.0 Qt Version: 5.15.10 GPU: Advanced Micro Devices, Inc.

However, the workaround of switching tty sessions was okay since it restored the display while preserving the running applications. However some change in the latest plasma release broke the workaround, and I end up losing my running applications. Hence, I would be very thankful if it was somehow restored

I appreciate the honesty here, but bug reports are reporting the bugs themselves, and not when the workarounds for those bugs break. We can't offer support for workarounds, but we can potentially offer support for the bugs they're being used to work around. So please submit a new bug report for the actual bug. Thanks!
