This website (when scrolling) feels on Firefox Preview (Android) with WebRender enabled. https://webassembly-summit.org/speakers/
Without WebRender (or normal Firefox) it feels not so sluggish when scrolling. There's kind of a zoom on the pictures effect when zoomed into viewport, not sure if this is why.
I have a Samsung Galaxy A3 (2017) and enabled WebRender myself in about:config (just to play a bit with it).

I confirmed that this doesn't seem to be a problem on desktop or Adreno.
Same problem also on https://websummit.com/speakers
Scrolling with Firefox Preview Nightly with WebRender enabled is really stuttering.
With WebRender disabled the scrolling is fluent. Also fluent with normal stable Firefox on Android.
The https://websummit.com/speakers also has huge, many fotos like https://webassembly-summit.org/speakers/ - maybe that's the main reason.
I am the original reporter, so same phone specs.

Profile on Galaxy A5 2017: https://share.firefox.dev/2ZSGwD5
Scrolling is definitely sluggish, and there's a couple stutters which correspond to hundreds of milliseconds glCopyImageSubData calls in the profile. Need to get to the bottom of this before shipping to Mali-T. It's fine on Mali-G.
