Ok, I know you guys are working on this, and it looks like the same issue as here:
So I suspect that for some users it causes a crash, and for others just a slow-down.
Just pinging here to also point out that these warnings seem to have started recently as well:
Main Thread Checker: UI API called on a background thread:
With a stack trace that seems to indicate that just the typical gl rendering (with only one documentWindow in this case) is being called from the wrong thread. I am not calling it directly, but have set the continuousRepaint().
I assume that is a related issue.
Thanks for working on it, openGL is always rather painful, but I’m sure there will be a solution soon enough.
