fading using fill() with OPENGL

apparently it's a non-bug (WONTFIX) that using the fade trick with OPENGL doesn't always work, due to inconsistencies in drivers.

fading: http://processing.org/hacks/hacks:fading

issue: http://dev.processing.org/bugs/show_bug.cgi?id=1054

Fry's suggestion on the bug page of using hint(DISABLE_OPENGL_2X_SMOOTH) didn't work for me (Macbook Pro, Radeon X1600, OSX 10.5.8), but I just added   hint(DISABLE_DEPTH_TEST); straight after it in setup() and this seems to have fixed the problem.

i.e. both of the hint() calls...

Code:
size(1000,800,OPENGL);
hint(DISABLE_OPENGL_2X_SMOOTH);
hint(DISABLE_DEPTH_TEST);


YMMV

GLfade doesn't work here. i get a white square that follows the mouse on a grey background but no obvious fading.

Windows XP, ATI video card (Asus X1550 Driver v8.33.0.0 apparently)
