Hello, Thank you for pointing out xscope, I didn't know about it. I ran my app under xscope and the first thing I noticed was that there were many DAMAGE-Event related messages, about 90 groups of them per second. So on a hunch, I disabled DAMAGE in X and the problem of the constant chatter went away completely, the CPU went to 0%-1% with tabs in the app and gtk.events_pending() returns False as soon as the window is rendered just like I expect it to. The output of xscope is very verbose, so what arguments do you recommend I use to narrow down the output to something useful? I was attempting to find a repeating pattern that I could post here, but the damage events all seemed to be mixed in with a lot of stuff that doesn't have a short term repeat. So, here is a semi random excerpt from the log that looked like it might apply: Thank you, -Neil-
