when going fullscreen the guest screen is stretched (Scott Bradford)

[cordney]

When entering fullscreen mode with a smaller guest screen resolution than the native one, the screen is stretched to fit the native Mac screen resolution. This leads to the guest screen looking blurry and - especially on 16:9 or 16:10 screens of newer Macs - guest screen proportions being distorted.

For those screen it would be better to: 1) don't stretch them at all (black bars all around the guest screen) OR 2) stretch them to the max native screen size available but still keep the guest's proportions (i.e. stretch to max height and then stretch width to keep proportions). that way we'd only have black bars on the left&right side

+1 for solution 2)

The only reason for 1) I can think of is avoiding distraction as the guest is already displayed 1:1 in its window.

1) we maybe look for good scaling factors (1.5,2,3) to prevent moires 2) we will honor proportions of guest
