--- Comment #3 from Matthew Cline <m...@nightrealms.com> --- Created attachment 138494 --> https://bugs.kde.org/attachment.cgi?id=138494&action=edit Old kwinrc which was causing the problem The problem was caused by an old $HOME/.config/kwinrc file, as moving it away so a new one can be generated fixed the problem. At a guess I think the issue is the [Compositing] section with "Backend=XRender", but I'm attaching the whole file so someone can figure out the exact cause. -- You are receiving this mail because: You are watching all bug changes.
