I bisected this issue which pointed at it being introduced in: commit 12579fe71b3b8f79eb9c1b80e429443bcc437dd0 Author: Olivier Fourdan <[email protected]> Date: Thu Oct 6 16:49:39 2016 +0200 gdkwindow: configure native windows in move_native_children() ClutterEmbed on Wayland uses a subsurface and relocates it on configure events, but when placed within a scrolled window, no configure event is emitted and the ClutterEmbed subsurface remains static. Emit a configure event for native windows in GdkWindow's internal move_native_children() so that custom widgets relying on configure events such as ClutterEmbed can relocate their stuff. Similarly, when switching to/from normal/maximized/fullscreen states which change the shadows' size and possibly shows/hides a header bar, we need to emit a configure event even if the abs_x/abs_y haven't changed to make sure the subsurface is size appropriately. https://bugzilla.gnome.org/show_bug.cgi?id=771320 https://bugzilla.gnome.org/show_bug.cgi?id=767713 Oliver do you have any ideas or hints on how we should proceed to identify the proper fix?
