How do I fix icons become blurry after changing the taskbar size?

I changed the taskbar size in windows 11 following the guide here and it worked, however, all the app icons became blurry and didn’t scale correctly…

I set the TaskBarSi value to 2 in the registry entry.

I guess this is not an intended use case as we have to edit registry to change the size of the taskbar, but still wondering if there is a way to fix it.
