Restore and maxmize is rather ugly (black patches, twitchy)

[electrifice]

I'm using compiz on a recent upgrade to FC6 (from FC5) with driver 9631, obtained through yum kmod-nvidia-96xx. My GPU is a Nvidia Geforce2 MX 400 (64 MB). My DE is XFCE.
I am trying to fix a couple issues... 1) Some windows, like Firefox and Openoffice, act abnormally upon minimize/restore. Portions of the restored screen have black patches that go away almost instantly but make the restore rather ugly and not smooth. 2) Maximizing windows also isn't smooth... they tend to twitch and even though the frame maximizes itself instantly, the insides of the frame resize a second or so after.
Maybe these are known bugs with the compiz release I'm using (0.3.6), but I'd like to fix this if possible.
Thanks

The same problem here. I got it after updating to the newest version 0.4.0 (I think it was OK with 0.2.2). I use Suse10.2.

This issue is not specific to compiz, I think. I also have an nvidia card. Before using compiz, I used to use the kde composite manager (kompmgr) with kwin. When I upgraded to Ubuntu 6.10 from version 6.04 (bringing xorg 7.2 in with it, I think), I started to get this thing that Firefox and Thunderbird windows would be black for a short time during unminimizing, before being correctly redrawn.

I never saw this in Ubuntu 6.04, but see it often with 6.10; and it happens with every composite manager I have tried. I think a faster machine and card makes it less noticeable. I don't think it is anything to do with the version of the nvidia driver (I've tried several older ones with kwin under Ubuntu 6.10). Perhaps it was a change in xorg.

i think that is related to compiz...i use an ati card and i was used compiz until i get the same problems(maybe bugs), in fact the 0.36 version was works for me with none of this issues but it's starting to happen in the 0.4 release...can anyone explain to us what could be the problem or lead us to the solution?

opensuse 10.2, axgl, ati , gnome
