The backtrace lacks debug symbols. Can you please install debug packages and submit a new backtrace? Tried to reproduce with debug symbols installed. kwin_x11 didn't crash this time but kwin_x11 and plasmashell consume 100% CPU Interesting... Can you please still post kwins backtrace? Relevant wiki page: https://community.kde.org/KWin/Debugging Here an udpate: I am using a Thinkpad T580 with a ThinkPad Hybrid USB-C with USB-A dock which uses DisplayLink. The problem I encountered yesterday was when I attached 2 external DVI displays. I believe the problem might have to do with the fact that I didn't have the dock connected to the Thinkpad at power on and/or DisplayLinkManager was not running when logging in. Later yesterday, support replaced those old DVI displays with two new ones using HDMI. Now, I can no longer reproduce the problem... Created attachment 122399 [details]
kwin_x11 backtrace
ok, waiting a bit longer I see kwin_x11 using 100% cpu even with 2 HDMI displays attached. I am using deb http://ppa.launchpad.net/kubuntu-ppa/backports/ubuntu disco main/debug but I wasn't able to get all debug symbols, eg: E: Unable to locate package libqt5gui5-dbg E: Unable to locate package libqt5gui5-dbgsym Where can I get these? I'm sorry but I don't use Ubuntu. I suggest to ask that question on support forum of your distro. 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! On Kubuntu, currently the debug packages don't match the installed packages. Hence I was not able to get annotated backtraces. In the meantime I switched my docking station and also changed attached displays. I didn't see the reported issue anymore. I suggest to close this bug report. |
