-- Information about the crash:
So after #499383 got fixed, (thank you very much for that by the way), I still have plasmashell crashing when I power my two monitors. One is a TV screen and one is a regular PC screen, and I suspect there may still be some timing issue where plasmashell will crash when I turn the slower starting TV on first and then the other screen in rapid succession. Hopefully this backtrace will be useful, and if not, please tell me what additional information you need or want to figure the problem out.

The crash can be reproduced sometimes.

Comment 3 Magne Djupvik 2025-04-07 20:24:56 UTC

I'm very sorry for the additional duplicate. I managed to confuse myself and thought the crash was fixed in 6.3.4, but your blog clearly states it's fixed in 6.3.5. My mistake. 
Thanks again for all your hard work.
