> If memory serves, app_server allocates a frame buffer region double the
height of the visible area, and then the lower half is used as back
buffer.
This would make sense in the context of what I have seen on the R61. Maybe
it uses a wrong height somewhere.
> I think a good criterium should be the memory writing (and/or reading)
speed to the video card memory. Should be easy to check and implement and
then it just needs more testing one a broader range of hardware.
To me it seems this depends on the driver used rather than the hardware
generation, i.e. the intel_extreme and s3 seem to work fine, but some
others, like the radeon_hd don't (yet?). Couldn't this possibly be enabled
on a per-driver base?
