Thanks to everyone who tried out the change in 2.8.3_beta3 (and 4) and provided feedback. I'm glad to see that these changes have addressed some longstanding crashes and some drawing issues. I believe all the reported regressions from these changes have been addressed in beta5: https://www.xquartz.org/releases/XQuartz-2.8.5_beta5.html Please do continue testing and providing feedback (especially if you see a regression compared to earlier versions). Thanks, Jeremy
