Advice of data point permanence

[zkwbbr]

I am using the ff. data points to generate a fingerprint:

getBrowser()
getOS()
getOSVersion()
getScreenPrint()
getTimeZone()
getLanguage()
getFonts()
getCanvasPrint()
getEngine()
navigator.hardwareConcurrency
navigator.deviceMemory
navigator.maxTouchPoints

To me this looks "permanent" enough unless there is major change in the user's device. However some users still occasionally experience a different fingerprint. Are there any data points from the above that might change in case a user's browser updates?

For those who care, I've found out during testing that the JS property screen.availHeight can potentially change during a browsing session by a few pixels even if the user doesn't do anything. I believe this is what's causing the issue in my post above.

This property is used by these clientJs methods: getAvailableResolution() and getScreenPrint().
