Normally, the SDL output window for a VM resizes to match the VM's resolution. However, intermittently the output is instead scaled within the window. I can't seem to find any pattern to when the output is scaled versus when the window is resized. I would prefer that the window be resized as needed to display the VM in a 1:1 manner.
The Ubuntu report for this can be found here: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/504368
Sorry, should probably have included the version of KVM:
$ kvm --version

$ apt-cache policy kvm
kvm:
Installed: 1:84+dfsg-0ubuntu16+0.11.0+0ubuntu6.3
Can you reproduce with qemu-kvm-0.12.x?
Can't say with absolute certainty yet, have only been using 0.12.2 since a while after your message. However, so far I haven't seen a single instance of scaling and I've tried stopping and restarting a number of different VMs. So, at this point it looks much better.
Just happened again under 0.12.2. It's much less frequent than before (or seems to be) but still happens.
