[WoW Anniversary Realms] Graphical bug every time I get an HK

I am getting a graphical glitch every time I get an HK in classic wow where the background flickers almost like it does when your graphics card is on the fritz, but I can only get it to trigger this problem when HK’s occur. This error happened to me in SoD in the past but I hadn’t noticed it for the past few months. Now that I am leveling on Nightslayer the error has started again.

Here is a thread that details the error a little better as well.
