Jeff, is it expected that gradient rendering is dependent on the destination surface size in some way?

Comment 2

[Jeff Muizelaar [:jrmuizel]]

Yes, bug 966996 caused some of that. It might be worth reverting the clip extents part of that patch to see if it helps.

It's also very believable that gradient drawing could not be start position invariant. Skia's implementation currently has this problem.

Unfortunately that didn't help :(
