Description

Attachment: test.html

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:78.0) Gecko/20100101 Firefox/78.0

Steps to reproduce:

Just load the attached HTML file and watch

Actual results:

The content of the box changes from 0° to 30° to 60° to 90° to ... to 360° unevenly. Some of the steps are even skipped altogether.

Expected results:

The number of degrees shown in pink rectangle should change evenly from 0° up to 360° (in steps of 30°) as the rectangle spins around.

This works perfectly in both Chrome and Edge. (I haven't tested Safari.)

To give you and idea of the speed of my machine, it's Intel Core i&-4790K @400GHz, NVIDIA GeForce GTX970 running Windows 10/64bit, Firefox 78.0.2 (64bit)

I can no longer reproduce this problem on my own machine, so I assume something else was screwed up when it occurred, but I don't know what. Please ignore this bug report. If I see the same thing again, I'll try to track it down. Thanks - Paul Mason
