Driver bugs...

Thanks to Dmitri, who suggested that both bugs I am experiencing are probably due to incorrect pixel/texel mapping. XRender itself is pixel-based, so the driver is responsible for the mapping.

The nimbus-corruption shown below is fixed in Xorg-1.5/Intel-2.3.2, however there is another bug where scaling on the x-axis only also blurs pixels on the y-axis when billinear filtering is used, and its still there in the setup mentioned above.
Switching to XAA (software scaling using pixman) did not show the problem.

Thanks again!
