--- Comment #3 from Mircea Kitsune <sonichedgehog_hyperblas...@yahoo.com> --- Following a suggestion on the openSUSE bug tracker: I switched to the default Breeze KWin theme followed by logging out and back in. No change, issue still occurred. Attempting to start a test session with "LIBGL_ALWAYS_SOFTWARE=1 dbus-launch-session startplasmacompositor" wasn't possible as dbus-launch-session was reported as an unrecognized command when I looked at it. However I could solve this by adding "export LIBGL_ALWAYS_SOFTWARE=1" to ~/.profile then starting a new session normally: I can tell it worked since all desktop effects were disabled and the mouse cursor was extremely laggy (everything felt like it ran at 5 FPS). To my surprise even this didn't affect the issue, both the missing windows and session crash could still be reproduced after a number of attempts. -- You are receiving this mail because: You are watching all bug changes.
