Blender 2.55 Beta Buttons Redraw Error?

I either discovered a bug within Blender or perhaps more incompatibility with certain graphics cards. I noticed that while Blender 2.55 runs quite nicely in some regards, whenever I go to the lower window and go to the Properties view, and go to something like Modifiers, every once and a while, the program will all of the sudden zoom into the panel (sometimes triggered via a middle mouse button drag to pan the view or sometimes just simple scrolling) and all the buttons are all displayed in some funky overlapped fashion. Is this is a bug or some setting I need to adjust within the software? What can I do within Blender to make this very annoying issue go away (I can’t zoom out or anything for that only makes the buttons look weirder/more overlapped and messed up)?

EDIT: Attached is a screenshot of what I mean by the buttons messing up seemingly at any trigger of the middle mouse button.
EDIT2: One way to solve this problem is to hit the “Home” button which does refresh things, but does not rid me of the middle mouse button triggering issue.

It’s probably a known bug, but 2.5x blender doesn’t do well displaying properties horizontally. The default UI shows them vertically, but opening 2.49 projects often results in these kind of problems. Rearrange your windows to show vertically and I’m 90% confident you won’t have any more problems.

I realize that may not be a very satisfying answer, but that’s how things have panned out for me…
