Subject: [PATCH] client: Disable threaded GL on desktop NVIDIA
Otherwise QtQuick windows freeze when resized.
In order to still use threaded rendering on
embedded platforms where resizing is not required
we check if XDG_CURRENT_DESKTOP which should be
set by desktop environments.
Task-number: QTBUG-95817
Pick-to: 6.6.2
