virtio-vga will adapt the guest display to the window size (once the guest drivers are loaded). Therefore it is not needed to auto-resize the window (to avoid display scaling).

Proposal: make "Zoom To Fit" unchecked by default for virtio as well Extended proposal: make GTK window options configurable via parameters To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1788701/+subscriptions
