Exiting seamless mode does not revert guest display back to previous resolution -> fixed after (not in) 6.0.4 and in test builds

[thoms]

In prior VBox versions (< 6.0), the behaviour when exiting from seamless mode was to revert the guest screen resolution back to its previous settings immediately before entering seamless mode. In 6.0.4 (and possibly 6.0.0 and 6.0.2 -- did not test), when exiting from seamless mode the guest screen resolution is set to full-screen, effectively forgetting the prior resolution settings.

I was about to file a bug report myself, but you were here first ;)

I did some testing today, and it's not seamless only, but full screen as well. Actually that's how the whole discussion started: ​Exit Full Screen doesn't revert to resolution prior.

The reason, as seen in the discussion, is that the 'ExtraDataItem name="GUI/LastGuestSizeHint"' value changes when in full/seamless to something that it shouldn't.

Tested with 6.0.4, it fails. Tested with 5.2.26, it works. Methinks it's a 6.0.0 regression.

Could you please give the current development (not 6.0!) test builds a try?

The 6.0 test builds now contain the fix too.

Just an FYI. "Methinks it's a 6.0.0 regression." I've been using VirtualBox since VirtualBox-4.0.8-71778 and I don't remember it ever doing this.
