STR: Opening https://paulstamatiou.com/work/ and scrolling down
AR: With and without WebRender scroll-triggered fade-in animations cause massive hangs.
With WebRender Nightly doesn't even recover enough to take a profile right now, but I keep trying.

Can you attach the contents of your about:support? I don't see the hangs on my Mac at first glance.

To get the janky behaviour on my machine I need to take care to make sure to generate the mouse over animations of the various elements while scrolling. If I just scroll down without that it goes relatively smoothly.

Confirmed on Windows 10 Reference Hardware (Acer) with WebRender on.
See all the elements and properties that animate on hover:
- Open Inspector and select
#twitter-threadselement - Open Animations tab in Inspector sidepanel
- Open the
:hovmenu and check:hover

It is janky with WR and on Chrome too on Linux for me.

I'm not able to repro this bug using the steps in comment #0 currently, performance seems fine for me, it's not even hitting blob rasterization time much (I assume this was blob images using too much memory or something originally?).

Comment 3 has a clearer explanation of the issue. Bug 1763821 has better STR so I will mark this as a duplicate (even though this report is the older one... :D)
