Possible Causes / Solutions

The problem is caused by the caching system that the PImage use when the FX2D rederer is on.
The image is cached with the last used tint value, that cause all the images being displayed with the same color, if they are refered to the same PImage.
The PImage should be probably cached once per color in order to allow the drawing of different tinted version of the same PImage.

Until this bug gets fixed, adding g.removeCache(); after applying a tint to a PImage is a possible workaround.
