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.
