Actually it always happens in Indiana Jones in wayland, I had to use X11 to actually play the game. It's the only way I know to be reproducible.

Does setting the "color accuracy" setting to "prefer color accuracy" change anything?

In the desktop, unsure, didnt see it happening again after this report. I changed it, if happens again, I will tell the results here.
