I get extreme slowdowns with this extension in Brave

[nextgenthemes]

I narrowed it down to this extension. My browser becomes unusable slow, like I can not switch tabs without an insane long delay it seems like something is running in a loop and overflowing things.

Not sure what I should provide for debug.

#2093 here is someone with slowdown (of a different kind if seems) and in Firefox. Maybe it's related. But what I get is really making the entire browser unusable slow.

Ubuntu 24.10
Brave Version 1.73.97 Chromium: 131.0.6778.108 (Offizieller Build) (64-Bit)

Did you try it with empty profile/default settings (of browser and extension)? Because nothing like that happens in my Brave on Ubuntu.
