gnome-shell/libmutter segfault when changing scaling factor

[Andreas Hasenack]

When I go to settings -> devices -> displays and change the scaling factor from 200% to 100% and hit apply, the whole desktop crashes and I'm back at the login prompt.

From dmesg:
[ 228.258624] gnome-shell[6787]: segfault at 8 ip 00007fa2ed24e877 sp 00007ffcdaafcd10 error 4 in libmutter-1.so.0.0.0[7fa2ed1a5000+141000]

This is a X1 Carbon with a 2560x1440 display and currently I have it at 200% scaling factor, as hidpi doesn't work properly in artful yet.
