I think I might have misunderstood both Raph Levien's comments on his 
previously quoted natural brush page, and the Gimp's source code (not hard to 
misunderstood, that). Judging from the documentation and code of the Seashore 
OS X gimp clone, the temporary layer where the brush masks are painted is as 
big as the layer one seems to be painting on; and the (whole? changed rect?) 
temporary layer is only composited using the chosen composite method on 

This would explain the behaviour Patrick saw in the Gimp and the preview 
windows; the delayed updating of the preview window wouldn't be due to not 
updating from the tiles and painting the window directly, but due to the 
delayed pasting of the temporary layer. At least, that seems likely.

Maybe I'll experiment a bit with a bigger temporary layer tonight, because I 
need some more elbow room for the effects of the pipe brushes anyway.
