[Intel-gfx] Flicker on current git master on first Xv (overlay) use

[Rémi Cardona]

Hi all,

Just a quick update on the whole flicker issue. With the current driver 
from git master, all flickering is gone... except the first time Xv is 
used. Again, this is on an 855GM (obviously using the overlay).

Anything I can do to help track this down?

Cheers

Rémi
