From: Dave Airlie <[email protected]> XRender defines this, GL really doesn't like it.
kwin 4.x and qt 4.x seem to make this happen for the gradient in the titlebar, and on radeonsi/r600 hw this draws all kinds of wrong. v2: bump this up a level, and check it earlier. (I assume the XXXX was for this case.)
