Not just kwin suffers horrible performance. On my AMD 760G integrated chipset, XBMC also suffers greatly. The XBMC built-in software video renderer is much (twice) faster than its advanced shader (GLS ) or basic shader (ARB?) video renderers. It's pretty frustrating.

A lot of application developers write their apps against 1 or 2 closed source drivers and never test the open drivers. GL is a huge API and it's hard to fully test all of it; just because something works one way on one driver, doesn't mean it will on all drivers. We'll do our best to fix any bugs that get reported.
BTW, I don't know if I compare apple and orange with respect to software vs GLSL video renderers in XBMC. My CPU speed is a 2.5GHz AMD Athlon 64 while my AMD 760G graphic card speed is set to only 200Mhz in the BIOS.
If I use fglrx, XBMC GLSL video renderer plays movies at full speed (24fps) but if I use r600g, XBMC GLSL video renderer plays at 15-20fps. My TV is at 1080p.

People who really need top performance should continue to use Compiz with KDE, like they do with Gnome. It works just fine. For me, KWin works just fine (but I'm not experiencing the problems the OP is, the last KWin issue was about a month ago for me).
KWin works perfect here too--only because I don't activate desktop effects.

you're not "disgressing", that's exactly the topic of the thread i started
brigdman: i am running r300g; says so in glxinfo.
RealNC: I knew it !!!1
since this thread as gotten all over the place, i suppose i may just ask this here without creating a new one: i'm trying to run a game that's asking for "s3tc" software compression. the mesa page says to use a 3rd party library, but the link to the source for the lib is dead. then i found out you could "enable" s3tc using driconf, but i think that's only for r300c. it doesnt look like it's working in r300g anyway; i have all options set to enable s3tc, and the game is still complaining that it can't find the extention.
