Is Plasma Mobile really slow for anyone?

I have it installed on postmarketOS edge on my Fairphone 4, and although I’ve been informed that hardware acceleration is supported (which I’ve confirmed via glxinfo), it’s a lot slower than the OEM’s AOSP distribution was.

Considering I used to have locgat loggers and cell tower trackers in the background, I wouldn’t have expected that Plasma Mobile could get slower with only waydroid installed, since I’d presume it’s a lot lighter. Consequently, I’d like to ask whether anyone here has experienced comparative slowness on similarly powerful hardware.

If not, I’ll ask at some of the undermentioned instead:

…unless anyone has better ideas, like how to diagnose it:
