--- Comment #4 from Stamatis Kavvadias <stamatis.kavvad...@gmail.com> --- I cannot send an updated backtrace because KDE Crash Dialog does not appear again. Your link for howto get symbols for the backtrace is wrong. I had to read a useless page (since I am not classifying this bug, just reporting it) to get to https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports, which instructs on how to get debug symbols. I found out I need to install kdelibs5-dbg. I do not know if I need to install symbols for kwin and which packages to install (kwin does not have any -dbg package available). Still I cannot produce and send a backtrace, if KDE Crash Dialog does not appear . kwin still crashes, after a few desktop changes. It is likely that the cube desktop switch effect and the multiple windows in multiple activities I have running, do not interoperate correctly, but I cannot tell you anything more. What should I do with this bug? Going back to Kubuntu 16.04 is my best alternative. -- You are receiving this mail because: You are watching all bug changes.
