Okay, if you're able to reproduce the crash, could you please install kwin debug packages and submit a new backtrace (with debug symbols)?
Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information. For more information about our bug triaging procedures please read the wiki located here: https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging If you have already provided the requested information, please mark the bug as REPORTED so that the KDE team knows that the bug is ready to be confirmed. Thank you for helping us make KDE software even better for everyone!
I cannot replicate it any more. It seems to be resolved, but I'll install kwin debug packages anyway. You can mark as RESOLVED since I can't reproduce it again after the last couple of full upgrades. Thank's for the work.
