Window movement feels very jerky
Last modified: 2006-01-12 17:52:24 UTC
Please describe the problem: With the new constraints code, moving windows feels very jerky, even in the absence of edges to "snap" to. Not sure if its trying to snap to phantom edges or if maybe there's some performance issue. But it definitely feels sluggish. Steps to reproduce: 1. 2. 3. Actual results: Expected results: Does this happen every time? Other information:
Hard to do anything without some more info. If you continue the movement operation for a long time, is it any faster (i.e. is it slow at the initial part of the move operation or throughout)? There are always edges for resistance, even if it's just the screen or xinerama edges. Are those involved when you see slowness? One thing to keep in mind is that there is more to the edge resistance than just snapping-to (or should I say, snapping-past); there's also a snapping-away-from resistance -- Is there any chance that's the slowness? Anyway, I'm guessing it'd be hard to narrow things down this way, so maybe a binary search from some simple patches would help. Could you try the patch I'll attach in a minute and let me know if it fixes things or not?
Created attachment 57003 [details] [review] Step one of a binary search using simple patches. :) (Patch is meant for testing and feedback purposes only, not for committing, so I'm marking as commented-on)
I tried this with a patched CVS metacity that disables edge resistance and also with an old metacity and I think the problem is with X.org on the system I was using to test.
