reassign 377929 xserver-xorg-core reassign 327699 xserver-xorg-core forcemerge 327699 377699 close 327699 thank you This GLcore crash is actually a mesa problem in the server core (reassigning) and the same than bug #327699 (reassigning and merging). Both should be fixed now since upstream fixed this bug a while ago (https://bugs.freedesktop.org/show_bug.cgi?id=4087). Closing. Brice
