Solution: NVIDIA DLSS (Image Scaling) causes the issue! If you have this feature enabled in the NVIDIA settings, then try and fully disabling it in Nvidia Experience, or Nvidia Control Panel. Experience was enough for me. Even tho it is disabled for WoW, but still enabled in settings, it will cause the issue.
Just turn it on again after, it will take under a minute:)
I hope that this is the cause for you aswell, so it can be solved.
Pls report back with your results, even tho it didn’t work.
Pls read more detailed explanations and details on this post, dont wanna repeat it all:
