808623 - FishIE Tank performance has regressed

Status: RESOLVED INCOMPLETE

(Core :: Graphics, defect)

Description

[Joe Olivas]

Testing performance with the latest Nightly has shown that FishIE Tank's performance has regressed significantly. This has been happening for at least the past two weeks, but I can't pinpoint when it started.

Even running 20 fish is not running at 60 FPS as it does in the release version 16.0.2. This has happened on many of our test systems, but here is the Graphics section of about:support from my laptop, which also experiences the same issue:

Another observation: 

On the latest Nightly, with 500 fish, I am getting about 40-45 FPS, but when I move my mouse, it jumps up to ~55 FPS.

In addition, running with the Gecko Profiler, the FPS jumps up to about 55-58. Turning it off, it goes back down to 40.

regressionwindow-wanted still needed here. Any ideas why the Profiler and mouse movement makes the FPS go up?

The regression window can be determined with https://github.com/mozilla/mozregression
