I found some very odd behavior today while using the Terminal (I work in it a lot) that I'd never seen before. I just reformatted my HD and installed Snow Leopard on a clean partition, before using Migration Assistant to replace all my old goodies. I use SIMBL for color adjustments.
While two finger scrolling using my MBPs trackpad, the text in the terminal changes from green to yellow. The text in the direction I am scrolling remains green and fades to yellow. If I scroll slowly, only one line is green before turning yellow immediately. If I scroll quickly, I get a smooth fade from green to yellow.
I've never seen this before, it doesn't happen with the scroll bar, and I didn't see anything on a quick Google search. Has anyone ever seen this before or know what causes it?
