http://bugzilla.opensuse.org/show_bug.cgi?id=953566 Bug ID: 953566 Summary: KDE flickering and compositing broken Classification: openSUSE Product: openSUSE Tumbleweed Version: 2015* Hardware: x86-64 OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: KDE Workspace (Plasma) Assignee: kde-maintainers@suse.de Reporter: charles@mcevoy.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- After upgrade yesterday to Tumbleweed from 13.2 (which worked fine) Heavy flicker/tearing of whole KDE desktop, particularly when displaying overlay windows (eg logout countdown) Switching off compositing cures the problem, but I can find no combination of settings that allows compositing to be on without a problem. Intel i5-4670K using inbuilt graphics. glxgears works fine/glxinfo looks fine. Nothing on Xorg.0.log, nothing in journalctl, and only an (apparently) unhelpful "No such method 'compositingNotPossibleReason' in interface 'org.kde.KWin' at object path '/KWin' (signature '')" in the Desktop Effects - System Settings window after re-enabling OpenGL detection. -- You are receiving this mail because: You are on the CC list for the bug.
