8 months ago I just updated a website from Ruffle 2023-02-17 to 2024-02-15 and saw a massive performance loss, causing really nasty page lag.
So i went back, testing performance with various versions and found that the performance fell drastically on 2023-06-24.
My guess is it was the newly implemented cacheAsBitmap feature.
Here's one of the swfs I was testing: test.swf.zip
Describe the bug
In the latest builds (eg 2024-02-10) the performance is very poor. On the build I was using previously (2023-08-01) performance was much better.
Expected behavior
Decent performance like that from previous versions.

Affected platform
Self-hosted version
Operating system
Windows 11 and Android
Browser
Chrome & firefox.
Additional information
Open the webpage, start a new game, skip the intro (top right). Once the platform game starts, performance is poor.
The performance decrease is particularly noticeable when running on a mobile device (eg pixel 7) where it becomes unplayable where previously it ran very well. But the FPS drop can be seen on desktop in firefox as well. Chrome on desktop it seems to run fine.
Compared to the same flash file using an older rufflejs build (2023-08-01) where performance is vastly better: https://rubber.tube/games/timcredible/timcredible.html On mobile, or desktop firefox this version runs very well.
