I was doing a levelling roulette with randoms and when I got to the first boss, there were these weird square things when the boss was charging up its wind AOE attacks.

Then, I figured it could be graphic card driver so I updated immediately afterwards. Then, i went in to Mt. Gulg again with Trust companions and the glitches still persist.
