Subject: [PATCH xserver 22/24] xwayland: Call
|

xwl_window_check_resolution_change_emulation() on newly created O-R windows
|
|
|
3ae2631 |
|
|
|
3ae2631 |
Some clients, which use vidmode to change the resolution when going fullscreen,
|
|
|
3ae2631 |
create an override-redirect window and never trigger the screen->ResizeWindow
|
|
|
3ae2631 |
callback we rely on to do the xwl_window_check_resolution_change_emulation().
|
|
|
3ae2631 |
|
|
|
3ae2631 |
This causes us to not apply a viewport to them, causing the fullscreen window
|
|
|
3ae2631 |
to not fill the entire monitor.
|
|
|
3ae2631 |
|
|
|
3ae2631 |
This commit adds a call to xwl_window_check_resolution_change_emulation()
|
|
|
3ae2631 |
at the end of ensure_surface_for_window() to fix this. Note that
|
|
|
3ae2631 |
ensure_surface_for_window() exits early without creating an xwl_window
|
|
|
3ae2631 |
for new windows which will not be backed by a wayland surface and which
|
|
|
3ae2631 |
thus will not have an xwl_window.
|
|
|
3ae2631 |
|
|
|
3ae2631 |
This fixes ClanLib-0.6.x and alleggl-4.4.x using apps not properly
|
|
|
3ae2631 |
fullscreening.
