Citra issue Frame skipping random

[Benetnash0]

Does anyone else get weird frame skipping when playing this game (MHXX) ? The game speed stays at 100% and FPS stable 30-31, but it seems at random that it will begin to skip frames. I am on citra MMJ/antutu lastest..,

Edit*1 : I tried lowering the resolution from 3x/4x to 1x but the frame skipping always appears randomly and remains strange even when the shader cache has been collected...
