Emulator

What's the problem?

When I begin dumping frames with DX9, video output breaks. This happens whenever I check the "Dump Frames" option under GFX config, and I can even cancel a recording and the issue still occurs. This effects several Gamecube and Wii games, but not all of them.

Dolphin version with the problem (as it appears in the title bar, Ex.: "R
4779" or "R 6403M"):

r7571

(optional) Dolphin version that does not have the problem:

Operating system and version:
32-bit or 64-bit:

WinXP Pro MCE x86

Game ID (as it appears in game properties, Ex.: "GZ2P01" or "RSBE01"):

Various

Build command-line (not on Windows):

Was the ISO a plain dump from disc, compressed and/or scrubbed?

Compressed

I didn't used to have this problem. Specifically, it seems projections/floating point calculations are way off in some menus and it also seems several graphical options have been turned off: specifically in Mario Kart Wii, as I recall the black box in the lower left being a problem in previous revisions. I record gameplay videos on a regular basis with the framedump utility and have never had this issue before now. To my knowledge nothing has changed; I didn't change revisions, I didn't update/downdate any C++ or DirectX runtimes, I didn't update/downdate video drivers or video card. I didn't change any hardware or software whatsoever. Can someone help me find out what could be causing this?
