RadeonHD3850 artifacts - 10.04 alpha2

[Clemens Eisserer]

Hi,

I've just tested Kubuntu-10.04-alpha2 on my RadeonHD3850 equipped computer,
and I experience artifacts all and misrenderings almost everywhere.
Turning off desktop-effects makes the situation a bit better, but
misrenderings still happen.

Furthermore 2D rendering seems to be quite slow :-/

Is this a known problem, or should I report it?

Thanks, Clemens
