Comment 3 Leho Kraav (:macmaN :lkraav) 2016-12-04 15:41:38 UTC 
It looks like fixed by Red Hat https://bodhi.fedoraproject.org/updates/FEDORA-2016-45775f3dcf

Looks like upstream already has the commit https://cgit.freedesktop.org/xorg/xserver/commit/?id=59ad0e6a416d8e23f9d962af67a16ee28ec7867b
Comment 4 Lionel Landwerlin 2016-12-05 10:01:23 UTC 
Sounds like it is fixed indeed. Thanks!
