When casting Dreadwaters currently, you set a portion of the card appearing as an overlay in the screen on the lower or upper corners for the remainder of the match. It interferes some with play when it occludes your planeswalker portrait and health total.
Yeap got the same thing. part of the card showing up on the TOP left and BOttom Left of the screen. it goes away IF you clear all of the Trap Gem for DreadWaters. but comes back if you cast another one.
