In many cases, the effects in the game flicker. This happens when two or more effects are layered on top of each other. It looks like the game can't decide which effect should be on top, so it keeps flickering between them.
Examples:
-Using the Boundless Storm skill, the smoke and light effects flicker randomly, with one or the other on top at any given moment.
-Smoke coming out of a vent on high isle.
-The explosion effect to the left of my character during the volcanic vent world event.
