Here's a problem I noticed playing Resident Evil 4 (NTSC-U); not sure if it's a game specific problem or not.
When a non-native internal resolution is being used, there's a sort of "ghosting" effect around objects; this is especially noticeable on anything that moves. The effect grows worse as the internal resolution increases; 4x ghosts worse then 2x. Every gsdx hardware backend is effected; tested with OGL, D3D11, and D3D9 for kicks and giggles. The software backends are N/A since they always render in the native resolution and are not effected by this issue.
Here's a link to an example from Resident Evil 4, OpenGL HW backend at 4x native resolution, latest developmental build of PCSX2:

The effect is clear around Leon's gun, though you can also see it around his outline.
Enabling the Half-Pixel offset hack (normal works fine) more or less eliminates the problem.

If this is a game-specific thing, then this should probably be added to the game wiki.
