-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.
