--- Comment #14 from Thomas Lübking <thomas.luebk...@gmail.com> --- looks like a bug in the intewl driver (where the original report was EGL on radeon, it's only the same symptom) could be a dead lock, run "thread apply all bt" to dump all threads. Also you best install debug symbols for mesa (and intel-dri) to see which GL call is lingering around there. I doubt this came with an update of KWin but rather the kernel or mesa or the intel driver. Maybe a reconfiguration (uxa/sni/glamor or using) Please open a new bug in any case, you're wrong here ;-) -- You are receiving this mail because: You are watching all bug changes.
