This partially reverts commit 77bf310084dad38b3a2badf01766c659056f1cf2
which causes some guest display corruption when gtk-gl-area
is used for GTK rendering (e.g. Wayland Compositor) possibly due to
simulataneous accesses on the guest frame buffer by host compositor
and the guest.

Fixes: 77bf310084 ("ui/gtk: Draw guest frame at refresh cycle")
