[Mesa-dev] Pending issues of lollipop-x86

[Mauro Rossi]

Hi,

Marek's patches solved Camera and Youtube crashes on nouveau and radeonsi.
I'm available to test on i965, if needed

I think at this point the remaining major problem for lollipop-x86 is the
font artifacts/invisible chars on i965GM (X3100)
still present in mesa 11.0.0, I need to check with 11.0.1

Mauro
