Description of problem:
gnome-shell crashes with SIGSEGV (SEGV_MAPERR) as soon as the pointer is moved after login. Downgrading mutter and gnome-shell to 50.2-2.fc45 makes the crash go away; nothing else is changed. Setting MUTTER_DEBUG_DISABLE_HW_CURSORS=1 also avoids the crash on 51.alpha.		

Version-Release number of selected component:
gnome-shell-51~alpha-1.fc45
