[Impact]
Corruption is seen on windowed 3D apps running on dGPU
[Test case]
Get a certain Intel/AMD hybrid machine, run 'DRI_PRIME=1 glxgears',
see how the window has corrupted gfx.
The fix is to patch Intel i965_dri driver.
[Regression potential]
There could be a slight loss of performance, but corruption free
behaviour.
