Looks like canvas issue. Windows10+Intel HD 5500 mobile iGPU
Without remote canvas: https://share.firefox.dev/2PyY2Hg

Perf is still bad with remote canvas

Jeff, is this known?

Comment 5

The game uses fillText and strokeText while the canvas shadow properties are set. So we construct an intermediate DrawTarget to apply the shadow, on every call to fillText/strokeText.

Does "depends on bug 1560450" mean, the regressing bug is bug 1468801 ?

Comment 7

[Kelsey Gilbert [:jgilbert] (previously Jeff)]

Probably, but it's not a useful dependency for us here. Bug 1560450 is the core "there was a regression" bug. Most of these bugs could be duped to 1560450, but I want to keep them distinct for now.

In an attempt to get the regression range, I've noticed a huge improvement in the usability of the game/site.
As reference, the same load timers are on 67.0a1 (2019-03-03) and 78.0a1 (2020-09-20) are similar to other browsers such as Chrome.
