Delirium potion visual glitch

Hello!

Recently, I'm experiencing a visual bug when I'm at Delirium maps.

When I'm at a Delirium map, every time I use any kind of potion, the my screen kinda freeze for a split second, as if I'm like 50ms lagged. The screen glitches and blinks for a split second, and then it becomes normal again.
Dunno if someone else is having this bug.

I've tried doing a lot of testing on the fog, it only happens when I use potions. Standing still, moving, being afllicted with any kind of ailment or not, doesn't matter.
