Hi, I have made a small patch that add a -no-frame option to qemu.
It makes SDL open the window without a frame allowing qemu to use the
entire screen without entering full-screen mode.
When this is combined with the tablet usb device it allows changing to
other workspaces without first toggling from full-screen and
potentially ungrab the mouse afterwards.
If your window manager does not allow you to move windows without
frames the SDL_VIDEO_WINDOW_POS environment variable can be used to
place the window where you want it like this:
export SDL_VIDEO_WINDOW_POS=0,0
There is a screenshot of this change in action here:

I hope this is worthy of being committed to the official qemu.
