Strange Rotation Bug

I just installed RetroArch, and it works wonderfully except for one issue. Whenever I maximize the emulator window, the image rotates about -135° and stays that way until I quit and restart. Oddly, fullscreening the window doesn’t cause the issue, only maximizing. This issue also occurs immediately upon starting up if I run the emulator while using the render-to-texture setting for 2-pass filters. This seems to happen regardless of which core I use. Any idea what’s going wrong? I’ve tried turning off and on nearly every video setting I can find and nothing seems to fix it.

Here’s what it looks like:

Yes, that’s a known issue with the 0.9.6 release. I made an updated build that should fix it. You can get it here: http://www.mediafire.com/?jc9v2jiuqs8cb7e <32-bit http://www.mediafire.com/?k15h5l29ou51i8o <64-bit

Thanks a lot!
