<pre>Hi Denis. I did some quick testing, having disabled the fullscreen mode in the
game. Performance was notably reduced, presumably due to no longer being
unredirected, but no hangs occurred. After subsequently re-enabling the
fullscreen mode, a hang occurred within a minute of play.
I was surprised to find that the artifacts I previously mentioned became
visible as soon as I switched off the full-screen mode. I shall carry out some
more in-depth testing this weekend, including the use of the apitrace tool that
you kindly mentioned.
For what it's worth, I don't have any apparent issues with the use of
DisplayPort in my operating environment, as long as I avoid Wayland. Docking
and undocking works, other unredirected/fullscreen applications seem to work
reliably, Gnome's compositor seems to behave etc.</pre>
