Release 99.0.4844.84 has borked my JS canvas library. Currently working on a fix - it was my misunderstanding of the purpose of the CanvasAPI willReadFrequently flag that left the library open to a severe speed degradation.

In my defence the documentation implies that the willReadFrequently flag is only a hint to the browser, to take a different approach when performing getImageData() operations[1]. However setting the flag to true also impacts drawImage() functionality[2].

I tried reporting the issue as a bug last night - at the very least the issue needs to be documented - but the form for reporting issues kept collapsing on me so I gave up.
