Graphics glitch issue

Hello,

So I've been having a lot of trouble with Hearthstone lately, but MOST frustrating is a graphics glitch where a static-y looking mess appears above the hero portraits when some spells are cast. It's frequent and very bothersome - any thoughts on what's causing it or how to fix it?



Please help.

Thanks

I didn't find the right solution from the Internet.
