Blur all except matching - Causes stutter on nixos

[EliteAMDGamer]

On NixOS, only on wayland when you set Blur all except matching. When you have more then 1 virtual desktop set. on the first v desktop you will get some pretty incessant stutter, when opening a browser or game. You can go to another virtual desktop and have no issues.
Also the same cant be replicated in x11 or arch wayland/x11. I installed a fresh copy of kde nix this weekend and had the same issue.
I looked into it via the kde forums. As for why it only happens on Blur all except matching. I cant say i did have crystal dock in the list on the old system and the new one only has the stock "Class1/2/3" and I still had the issue. It's like this below.

This is probably a duplicate of #160, try adding xwaylandvideobridge to the class list.
