Subject: gdk/wayland: Avoid idempotent wl_subsurface.set_position calls
X-Git-Tag: archive/raspbian/3.22.24-2+rpi1^2~1

gdk/wayland: Avoid idempotent wl_subsurface.set_position calls

These may not result on wl_surface.frame callbacks, yet we do trigger
a frame clock tick that would get stuck on the lack of such callback.
