Description

Easiest to explain this defect with some screenshots (from the opengl backend)
Open both of these in separate tabs and switch between them.

Apart from Real XFB looking just looking worse in general, you should see that the contents of the bottom right triangle are offset to the left by a pixel or so.

DirectX 11 has similar problems, but they aren't as bad as OpenGL (possibly only 0.5 pixels off)

We had a discussion on IRC and both neoBrain and degasus have noticed this, yet have been too lazy to file a bug report, so I've CCed them. According to degasus, efb2ram is affected too.

Looks like this problem is a regression since 3.5, oh and DX9 works fine.
