Dark and blotchy UI overlay

[TagCdog]

Hi All,

Not too long ago I started getting this weird dark/textured/transparent full screen overlay. It goes away if I resize my window.

I think it could be addon/anchor related because I also started occasionally getting weird window discontinuity like this where the TOM window overlay is seperated from the actual location of the TOM addon.

This might be related to my previous posts regarding anchors and crashes. I have tried freshly reinstalling all of my addons and deleted my SavedVariables many times so I really don't understand what is going on here.

Does anyone know where that dark/textured/transparent overlay originates from (regardless of this error/bug)?

Is there a specific addon that I should target with troubleshooting?

Thanks!
