[Qemu-devel] [Bug 504368] Re: sdl window intermittently scales instead of resizing

[Anthony Liguori]

You can disable scaling by hitting ctrl-alt-u.

What's probably happening is that the window manager is generating an
extraneous scaling event.  I'm going to move this to wishlist as we
should provide better user controls of this behavior.

Bug description:
Binary package hint: qemu-kvm

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.
