Description Dave Airlie 2010-06-10 20:33:20 UTC 
Description of problem:

At boot we do the cool spinner circle, then when gdm starts we pop up the spinner busy cursor. This cursor looks fairly pixely and not near as cool at startup and I'd expect after the cool ring.

Comment 3 Jakub Steiner 2010-07-12 07:41:00 UTC 
I believe the 'pixeliness' is introduced to the cursors during the xcursorgen conversion -- it probably pre-multiplies alpha onto black. While you can't see it on the PNGs, it only seems to be happening on watch and left_ptr_watch cursors, which are generated by compositing the spinner animation onto a round base with imagemagick/graphicsmagic. Will investigate.

Composited PNG doesn't seem to be jaggy, so it looks like xcursorgen is to blame.
