Connor - do you think this is a regression? If so, can you find a regression window?

I don't believe this is a regression, I tested with WR from ~2 years ago and it has the same issue.

We probably need to do something along the lines of the todo here: https://searchfox.org/mozilla-central/rev/278046367dab878316f60f0bd7f740cf73f3c447/gfx/wr/webrender/src/picture.rs#4683-4684

I managed to get a regression range on this issue but its not very accurate though since I got the Not enough data to bisect message.

Nical, do you have a feeling about how to fix this?

I think that Connor's suggestion makes sense. The reason this was left as a TODO and not just fixed along with whatever the comment came with probably is that there was some trickiness involved but I don't remember very well. I'll have a look when we are confident with the work blocking shipping more intel GPUs.

Depends on D68230
