+Subject: [PATCH] wayland/egl: Ensure EGL surface is resized on DRI
+ update_buffers()
+
+Fullscreening and unfullscreening a totem window while playing a video
+sometimes results in the video subsurface not changing size along. This
+is also reproducible with epiphany.
+
+If a surface gets resized while we have an active back buffer for it, the
+resized dimensions won't get neither immediately applied on the resize
+callback, nor correctly synchronized on update_buffers(), as the
+(now stale) surface size and currently attached buffer size still do match.
+
+There's actually 2 things to synchronize here, first the surface query
+size might not be updated yet to the wl_egl_window's (i.e. resize_callback
+happened while there is a back buffer), and second the wayland buffers
+would need dropping if new surface size differs with the currently attached
+buffer. These are done in separate steps now.
