Why has text in P3D a non transparent rectangle around it?

hamoid

Hi, I made an example of rotating letters in 3D, but letters sometimes seem to have an opaque background of the same color as the last background() call.

Here is the code. https://github.com/hamoid/Fun-Programming/blob/master/processing/ideas/2014/02/textCloudRotating/textCloudRotating.pde

Here you can see what I mean by looking at the letter A.

Did I forget something? Is this an issue with Processing? Is it my graphics card?

Thanks!

hint(DISABLE_DEPTH_TEST); seems to fix the issue.
