I have of course contacted the site owner, but since the work is done voluntary - they do not have the resources to dig into the root cause.

The Bugbug bot thinks this bug should belong to the 'Core::Privacy: Anti-Tracking' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

The canvas randomization could cause the random figures. Would you be able to check if setting the pref privacy.fingerprintingProtection.overrides to -CanvasRandomization fixes the problem? Thanks.

It does - thanks Tim. Can resolve or update the default configuration to include that setting.
Cheers,
