[Intel-gfx] artefacts on 855 graphic

[Alexey Fisher]

Hallo all,

i know it is known issue that 855 is not really working with current
driver. But i wont to know if there is work in progress or any interest
of back reports?

I just had access to the laptop of my friend. It is in really bad shape:
by default vesa driver is used - even simplest video take 100% cpu
if i force intel driver, compiz make really wired artefacts - each
window can just disappear
if i disable compiz. it will sort of work, but has some other artefats -
part of old interface mixed with new, to make it disappear i need to
minimize and maximize window.

Regards,
