I think your theory very much explains the variance! Here are the
results with your patch applied:

[  1]    image-rgb      paint_radial_rgba_over-512   67718267   45.232
  46.363  2.24%  96
[  1]    image-rgb      paint_radial_rgba_over-512   67612712   45.160
  46.055  2.52%  98
[  1]    image-rgb      paint_radial_rgba_over-512   68089172   45.479
  47.044  2.39%  98
[  1]    image-rgb      paint_radial_rgba_over-512   68510858   45.762
  47.235  2.43%  99
[  1]    image-rgb      paint_radial_rgba_over-512   68235767   45.571
  45.811  0.98%  92

Quite an improvement! :) Someone should really apply that patch.
