First of all, sorry for flooding the planet, I've changed my blog software and it screwed it up (or I did).
OK then, on to compiz stuff.
Compiz is looking really good for the Ubuntu 9.10 release. We're getting the bug count under control after letting it get crazy for some months and compiz is no longer the package with the single most bugs open.
We've also only got one GPU blacklisted this time around, the Intel 845. Depending on updates to Xorg we may not even need that. We've also turned off the Unredirect Fullscreen Windows option by default. This may cause some performance regressions in fullscreen 3D games on some GPUs (only one reported case so far) but it also fixes a lot of the bugs making those same games hard to play with compiz enabled. No longer will your panel show on top of your game, no longer will your screensaver turn on while you're playing a game, no longer will a notify-osd popup make you look up at the sky and get fragged, etc.
The goal for the bug count for compiz by karmic release is 350 and we're getting close. Beta testers will probably push it back up but I can't hate them too much. 
More coming soon...
