Here is a workaround for now. Put this in ~/.gimp-2.4/gimprc:
(show-brush-outline no)
I can confirm this works, but as you might guess, the whole brush outline goes away. When Gimp 2.4.1 is released, a slightly more sophisticated workaround will be present, where you can use:
(xor-color (color-rgb 1.0 1.0 1.0))
That will change the drawing mode gimp uses from XOR to INVERT, and the brush outline will work better.
These are just workarounds; new users are going to keep encountering this until the bug in the radeon driver is fixed:
