Monster Hunter Portable 3rd HD VER

[Archimedes]

Windows 8 64 bit, AMD 6870. I always use the latest rev, in this case v0.9.1-15 (it's still present). There are some times though when the issue is not present at all, same settings and all, very weird if you ask me.
It might be from the GPU, I heard there are problems with AMD GPUs in general.

EDIT:
So I made a little experiment and here is what I found out.
When I first start a instance of the emulator and start the game, the issue is not present, but here is the problem, you see, I like booting the game up in full screen. So? well let me tell you.
When I do that some little weird lines appear near the capcom and dolby logo. So what do I do? well I exit the game, not the emulator, and boot it again. TADA! lines are gone, but then the butterflying texture error appears.
So yea... story of my life.
