Re: Control fb problem on 8500

I don't think having to use ShadowFB with the fbdev driver is too bad
because it should generally enhance performance :)

I guess control is the exception. I found out it isn't worth the memory
impact. I once ran a complete x11perf run comparing with and without
shadowfb, and with shadowfb was overall slower. Some operations were
faster, though, but not in general.

Oh no. This is very bad.

But that was on 4.0, not 4.0.1, right? shadowfb on 4.0 fbdev treated me to
a ~5sec delay on logout while that nice grey pattern was drawn line by
line. Someone said it was due to a bug in shadowfb... and I'd assume it
was fixed in 4.0.1.
