Yes, this is related to PD extended - didnt know what tag to label it
under. Let me know if I can label it correctly. With regards to the
quicktime bug, well, the problem doesnt occur on a older GEM version (0.90
compiled Mar 06). Additionaly, the problem persists when outputing .jpg
format. Beats me. The two files attached have background colour set to 1 0
0.3. Guess which is the odd one out...?

This appears to be a bug with the TIFF writing component in Quicktime. 
Try adding a 1 after the file name to select JPG image writing.  Example
message: 'file $1 1'

could you please provide images (screenshots) on how it does look like and
how it is supposed to look.
(sorry for the added inconvenience).

furthermore: is this related to pd-extended? (or rather: why does this
issue have a 0.39.2 tag?)

An example patch is always very helpful, especially if it triggers the
problem every time that it is run.  Ideally the example patch would have
only enough objects to cause the problem, but nothing else.
