Emulator

Game Name/ID? Any

Graphics corruption appears when there should be nothing but black, for example when switching from a forced 16:9 aspect ratio to 4:3. The black borders are all kinds of garbled graphics. Here is a screenshot of the issue in SSBM:

Which versions of Dolphin did you test on?

Dolphin-2593

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?

This did not appear to happen on older versions of Dolphin. I'd have to do some testing to see exactly which commit caused the problem. It seems to have cropped up around the fullscreen OpenGL changes.

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)

Linux Mint w/ kernel 3.16
Core i7-4770K
Radeon R9 290
fglrx-updates (Catalyst 14.6 Beta)

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)
