SUMMARY *** Since upgrading to 5.27.1, I cannot log in to a Wayland session reliably. I am getting a black screen instead. I was able to get plasmashell to start up using plasmashell --replace at first, but now that is not working, either. X11 is unaffected- if I start an X11 session, then logout and start a Wayland session, sometimes it starts properly, except the screen scaling is back to 100% instead of 150%. When that happened, I tried setting the scaling to 100% and not changing it in case that setting was causing the problem, but it still won't start when I logout/login. I started a new profile, and I can log in to a Wayland session under that profile consistently *** STEPS TO REPRODUCE 1. Start up computer 2. attempt to login to a Wayland session 3. Optional- start Konsole, try to login with plasmashell --replace OBSERVED RESULT Screen flicks on and off 3 times, then gives black screen EXPECTED RESULT Plasmashell starts successfully SOFTWARE/OS VERSIONS Operating System: Manjaro Linux KDE Plasma Version: 5.27.2 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 Kernel Version: 6.2.1-2-MANJARO (64-bit) Graphics Platform: Wayland Processors: 12 × Intel® Core™ i7-9750H CPU @ 2.60GHz Memory: 15.4 GiB of RAM Graphics Processor: AMD Radeon Pro WX 3200 Series Manufacturer: Dell Inc.

Please attach log from when you run plasmashell --replace
(In reply to David Edmundson from comment #1) > Please attach log from when you run plasmashell --replace plasmashell is still not starting properly, but plasmashell --replace is now working. I tried to pull logs after failing to start, and after plasmashell --replace.

Do you want me to post any of the stack traces here?
Yes please. Can you bet a backtrace (not the full stack trace) of the latest kwin_wayland crash? For instructions how, see https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl

I do think there's some relation to display scale. It won't allow me to start the session at 150% scale, but if I set it to 100% and reboot it is starting fine. I can then change it to 150%.
Thanks, getting there. We're still missing debug symbols for kwin, and we need a backtrace of just the crashing thread, not a full stacktrace of everything. Can you install debug symbols for KWin, re-read https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl, and follow the instructions there exactly? Thanks again!
