With this relatively new chipset, it is also crappy:
VGA compatible controller: Intel Corporation 82G33/G31 Express
Integrated Graphics Controller (rev 02)
The regressions started to appear in F9/KDE4. Until F8, it was perfect
:/ Currently, garbage often appear on screen at random places if desktop
effects are enabled and open gl applications behave strangely when other
windows are opened over or under them.
I still didn't move on from F8 on my laptop because of this.
I don't know what happened to Intel driver :( I installed Fedora 10 to my
friends desktop and it's really slow (no effects!) with red stripes all around
the screen... I didn't have time to report it, next time I'll visit her I have
to look at this issue. With DE on it's almost unusable. Same for my netbook -
3D is incredibly slow (with older Xandros, it was OK)... Seems like
proprietary NVidia blob is still best driver for Linux even with gazzilions of
issues :( If you want more than basic 2d acceleration...
So now I'm not sure about defaulting DE on for F11 - or we should have first
login dialog when user can choose - more effects, less effects as it was in
3.x.
