Just a quick follow up: We've found that if we are in fullscreen Pharo mode on Linux and hit the ALT button twice, the Athens-based rendering speeds up significantly. The first ALT brings the Unity launcher to the foreground. The second ALT bring fullscreen Pharo back to the foreground. I'm not sure why this makes Athens rendering faster but it does. Perhaps that offers a clue as to what is slowing Pharo down in fullscreen on Linux.
