wayland: soften GNOME warning

We've had some serious issues with GNOME in the past, but since then
their compositor has undergone some major internal improvements. The
most severe one [1], random vsync spikes and mistimed frames, can no
longer be reproduced by the original author of the issue. There are some
minor UI-related things (lack of window decorations for instance since
there is no xdg-decoration support), but users don't seem to complain
about that too much and they aren't revelant to playback.

3.38 isn't out quite yet, but that should also fix playback issues when
on a multimonitor setup (the fix is in the master branch at the moment).
In terms of playback, the only real concerning issue is the lack of idle
inhibit so a warning is still displayed. But GNOME has their own
workaround that users can use for that so if anyone happens to complain,
we can just point them to that.
