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

[Michal Suchanek]

My window manager maximizes all windows. I am running kvm 0.14.

Initially the VM is displayed 1:1 in the top left corner leaving large
portion of the window black.  Resizing the window or rebooting the VM
causes the output to be scaled which is horrendous.

There are three issues here: there is no way to force the window to be
the size of the VM output nor is there a way to display the VM output
1:1 regardless of window size nor  is there any possibility to make the
VM output scale proportionally.

Pressing Ctrl+Alt+u definitely does not disable scaling for me although
it causes the VM output to disappear momentarily causing the window to
flash.

I guess setting window size  can be achieved with some WM hint (and
should be a command line option and possibly a option configurable from
the monitor). Obviously, not all outputs can set the hint and not all
WMs will respect it. However, setting the hint *and* resizing to the
desired size should give the correct size in most cases.

The other issue is that scaling does not respect aspect ratio leading to
horrendous VM output. I don't think there is any use case for non-
proportional scaling.
