Ooh I just tried it on my XP laptop, and by the time the red has got to the
top it's only 80% of the way there on Vista. My Vista box is about 10x
faster than my laptop so who knows what is going on.
Does it make a difference under Vista if you take out the
"ControlStyles.OptimizedDoubleBuffer" flag?
Also you are locking the bitmap for quite a long time (relatively), you
should literally lock, memcopy, unlock. Any processing should be done
outside of that on a separate buffer. Maybe it is holding up Vista somehow
when it's trying to copy the bitmap to the graphics card?
