Bug ID: 104806 Summary: plasmashell and other KDE binaries start to segfault after updating Mesa to 18.0.0 (radeon) Product: Mesa Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: ao@thurston.ru QA Contact: dri-devel@lists.freedesktop.org
With Mesa 18.0.0 'plasmashell', 'ksplashqml' and 'kmail' binaries segfault right after logging in into Plasma session, leaving coredumps behind.
If I downgrade Mesa package back to 17.3.3, everything works again.
I'm running Gentoo.
