Xwayland crashed with signal 7 in mieqProcessDeviceEvent()

[joculari]

Sorry, I wont be too much help. This error message just popped up. A few minutes before that my computer had a black screen and the ventilation was running at maximum level. I pressed the on/off button for 10 seconds and restarted the system, which went fine. Then this error popped up out of nowhere. I didnt have any additional problems.
