DGA2 is for root only. DGA1 too.

This symptom is when you display a 8bpp picture in a 16bpp mode. The

I have similar problems but not reproduceable at will : sometimes events
go very slow when in a windowed mode... But quiting the program and
running it again fixes the problem, so I don't know...
