17638,"Changing ""View -> Virtual Screen -> Use Host Screen Y"" does not respect the VM "" ""Full Screen Mode"" / ""Auto-resize guest"" setting combo",Maximilian Machedon,,"On an Ubuntu 16.04 multi-monitor machine that has at least 2 monitors of different resolutions. Start a VM (with guest additions installed) in full screen mode and using ""Auto-resize guest display"" on ""resolution 1"" monitor. Open the VM context menu (Host Key + Home). Select View -> Virtual Screen -> Use Host Screen and select a monitor with ""resolution 2"". The VM retains the previous resolution (resolution 1).

Expected behavior: The VM is automatically resized to the new screen resolution (resolution 2) so that it is full screen in that new resolution.

Known workaround: Use the VM context menu. Deselect ""Auto-resize guest display"". Open the VM context menu. Select ""Auto-resize guest display"".

I highly suspect that this can be reproduced on any guest/host combination and any video card driver, so I won't be attaching the log file unless necessary to debug, as it would take me some time to filter out some of the lines in it. I'm attaching the relevant lines I saw (I've included the lines triggered by me turning a monitor off and on again; the action is unrelated to this bug that I've been able to consistently hit for the past few months).",enhancement,new,GUI,VirtualBox 5.2.8,,,,all,Linux
