This commit is seperate from the previous one to make it easier to revert in the future. Basically, while working on making MSTOs per-head as opposed to per-head-per-connector I discovered these lovely issues: https://gitlab.freedesktop.org/xorg/xserver/merge_requests/277 https://gitlab.gnome.org/GNOME/mutter/issues/759 Note as well that Intel already has a temporary workaround for this in their kernel driver. So, unfortunately we need to follow suit to avoid causing a regression in userspace. Once these issues get fixed, this commit should be reverted.
