Radeon/KMS and KDE4
I am posting the first time here, so I apologize if that was mentioned already...
I activated KMS and compiled the git-versions of xorg-server, libdrm, mesa, xf86-input-ati (distribution: gentoo).
So far, all is fine, glxgears gives 1900fps (Radeon HD 4670) and I can play UT2004-demo without problems or graphical errors.
BUT: turning on the desktop effects does not work:
when using OpenGl the speed is so slow, that the system becomes unusable;
when using "XRender" I cannot use most of the effects, like snow or the desktop-switching-cube. It does not matter if I am using kernel 184.108.40.206 or a 2.6.33-rcX - problem is the same.
does anybody else experience similar problems and how do you solve it?
