Bug ID: 379681 Summary: Crash after turning off compositions with Alt+Shift+F12 Product: kwin Version: git master Platform: Neon Packages OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: compositing Assignee: kwin-bugs-n...@kde.org Reporter: jodr...@live.com Target Milestone: --- As the title says. I am no entirely sure it is a kwin issue, it may be a a driver one since i am using "amdgpu" driver on a r9 280x (tahiti) from padoka's ppa. Had to blacklist "radeon" in order to use it. Application: kwin_x11 (kwin_x11), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
