Is there a way to reduce lag?

You could say it's just the way the concept of themes works, but the lag is abyssmal. I have already disabled all blur effects, and it's still lagging, I suspect setting blur to 0 does not actually disable it?

This'll remove the main background blur altogether. Let me know if it doesn't improve things.

.layers-OrUESM {
    backdrop-filter: unset;
}

Oh okay, i'll try.

I have also been having issues when the UI bugs out with time, but that's unrelated i guess? The lag also increases with time, as if there is a memory leak.

backdrop-filter can be a buggy css property and could very well be the cause of this supposed memory leak, but it's the only way to get the transparent blur effect.

This'll remove the main background blur altogether. Let me know if it doesn't improve things.

.layers-OrUESM {
    backdrop-filter: unset;
}

I tried this, and it went pretty well! Are there any other things I can put in for performance?
