+From: Antonio Larrosa <alarrosa@suse.com>
+Subject: Disable GPU when using nouveau or running on wayland
+References: boo#1005323, boo#1060990
+
+Qt WebEngine uses multi-threaded OpenGL, which nouveau does not support.
+It also crashes when running on wayland, the cause is not yet known.
+Work around these issues by not doing GPU-accelerated rendering in such
+cases.
