I have an AMD Phenom II X4 940 with an Radeon 4870 that loves to crash when I turn on compositing. OpenGL works wonderfully until it crashes kwin. XRender chews up so much CPU I'd rather not have it. I have an AMD Athlon II X4 635 with an onboard Radeon 4200 that loves to crash when I turn on compositing. Both these boxes have SB700/SB800 chipsets. I use xdm on the former and manually run X on the other. Same problem on both. I did not have this problem in xorg-server 1.7 series.
