Despite the backtrace actually lacks the relevant info, it's a dupe of the most famous kwin bug (or rather mesa, eventually intel) bug ever. The driver has issues with several GL contexts and unredirection.... > enable "Suspend desktop effects for fullscreen windows" in kwin kcm ... and that's ultimately why this off by default. -> For clients that matter (games), use composite blocking, otherwise just keep the window redirected along all others. We had several considerations to dump unredirection. *** This bug has been marked as a duplicate of bug 252817 ***
