getCanvasPrint returns different results in portrait and landscape modes

This leads to two differing browser fingerprints according to current screen orientation on mobile devices.

Could this be taken care of when calculating the fingerprint or is the best solution to exclude the canvas from mobile device fingerprinting? (which would also mean letting go of a major uniqueness factor)
