BUG in Trails Module?

I think I may have found a bug in the TRAILS module.

I've been messing with star trail effects, and have noticed that with high values of STRENGTH the feedback builds up unevenly with the bottom left corner of the Magic Window, with it becoming brighter in an irregular area. (See Screenshot).

This is reproducible with different modules as the input.

Further testing with another module shows that it's actually showing this behaviour in all four quadrants of the screen to differing degrees:

I don't see that here. I left it running for 20 minutes or so and no build-up.

Very strange. Perhaps it's related to my video card. (AMD Radeon HD 6770M)

Thanks, I'll have a look. Generally AMDs tend to have more problems like that (compared to Nvidia). I'm not sure why.
