Graphics bug

Hi guys,
So i am currently playing WoW on mac OS. I have had a graphics bug where my graphics are going crazy at some places/dungeons on the map. I have no idea how to fix it and i tried a lot of ways to fix it, sadly none of them worked.

I have tried reinstalling the game, i also tried adjusting graphics but nothing worked.
I am using CrossOver to run the game. (Bottle program)

My specs are:

MacOS Big Sur Version 11.1
MacBook Pro 13-inch, 2019, Two Thunderbolt 3 ports
Processor 1,4 GHz Quad-Core Intel Core i5
Memory 8 GB 2133 MHz LPDDR3
Graphics Intel Iris Plus Graphics 645 1536 MB

Thank you in Advance!
