I think that the bug is deeper in the video code...
I should like to know the opinion of the developpers ?
The problems are still here in 3553 for lucid (last nightly build at this time). If your patch is really the right solution, why is it not included in the last version ?
This is a question to the developpers !
I can survive with this problem,
I can recompile with sergeynikitin's patches each time I download a new nightly build...
But if the problem can be definitely corrected, it would be better
