Monster Hunter Portable 3rd

[dxshadow1]

Hello, first time here but not the first time i'm using PPSSPP (which is an awesome emulator). I have an annoying graphical glitch in MHP3RD which makes the ground flicker with weird polygons-like forms on it. My fps is great, goes from 22 to 26 and 30, but those graphical glitches are just plain annoying. I also had this problem with MHFU but unchecking "Disable Alpha Test" solved it on there. Tried the same thing with MHP3RD but it didn't change anything, I mean MHFU and MHP3RD basically have the same graphics and engine, it should run as good as MHFU without the graphical glitches...No? If anyone knows how to fix this issue, i'd be extremely grateful, thanks!

EDIT: Provided a screenshot to show some polygon-like forms (there are way more in-game and they flicker) it gives you an idea of what the polygons look like.
EDIT #2: I don't know why my post got merged with another that didn't have any answers to my question but ok...
