Canvas image changes on a Chromebook

[Finesse]

A user encounters canvas fingerprint changes on their Google Pixelbook with Chrome 87. In order to reproduce on the laptop, they open https://fingerprintjs.github.io/fingerprintjs/ (it doesn't matter whether the tab is new or old) and reload the page. One image appears after a soft reload, and the other after almost every hard reload:

Another pair of canvas pictures appeared when the link above was opened from a Google Meet conversation:

The difference is the text spacing and positioning:

1st pair	2nd pair	Left pictures of the pairs

Other user reports:

• The canvas image is stable on Acer R752 with Chrome 85
• The canvas image is stable too on an unknown device and Chrome version
• I've tried to reproduce in Chrome 86 on Ubuntu 20.04 on a virtual machine, the canvas is stable.
• The canvas image is stable on Pixelbook Go.
• The canvas image is unstable on Acer Chromebook 314 with Chrome OS 80, 85 and 86 (my device)

Trying to mitigate it in d3e359c by extracting the text into a separate canvas image. The image with text is still used to calculate the hash, but it can be removed in a custom components hash function.
