From 01629caef21b77cfabc052408eb04699e4fa5143 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 4 Nov 2019 11:46:49 +0100 Subject: [PATCH xserver 15/17] xwayland: Call xwl_window_check_resolution_change_emulation() on newly created O-R windows Some clients, which use vidmode to change the resolution when going fullscreen, create an override-redirect window and never trigger the screen->ResizeWindow callback we rely on to do the xwl_window_check_resolution_change_emulation(). This causes us to not apply a viewport to them, causing the fullscreen window to not fill the entire monitor. This commit adds a call to xwl_window_check_resolution_change_emulation() at the end of ensure_surface_for_window() to fix this. Note that ensure_surface_for_window() exits early without creating an xwl_window for new windows which will not be backed by a wayland surface and which thus will not have an xwl_window. This fixes ClanLib-0.6.x and alleggl-4.4.x using apps not properly fullscreening.
