Triangles are created by RA8875 hardware accellerated macro and has several bugs, I already noticed in some 3d examples where I've used polygon triangulations and mainly in filled triangles.
I've already tried to fix the filled triangle bugs, it appears when 2 vertices are close and the result it's a gigantic rectangle, or in this case it create a nonsense object.
For get pixel I guess has something to do with screen resolution, the RA8875 works best with 480x272 because it maps the memory banks internally as separate pages but when used with higher resolutions it doesn't have enough memory so it uses strange mapping methods and (if you are using layers) change it color depth at 8bit but internally try to expand colors in 16 to save internal RAM. Many functions are affected, try to scale a uploaded font char will cause a mess and so on.
