So is it actually expanding the window to fill the whole of the screen, rather than keeping it at the same resolution but just the only window being displayed? That's definitely different from the Lion-and-up behaviour... >> and there are other problems with fullscreen still -- for instance >> if you fullscreen the window before the guest changes its >> resolution and then unfullscreen it afterwards, we forget about >> the fact the resolution changed and revert to the pre-change size. > > I haven't noticed this issue. Which machine emulator are you using? I use vexpress-a15, where it's quite easy to see because the screen resolution changes a little way into kernel bootup, so it's easy to fullscreen it before it gets there. You can also see this with qemu-system-ppc if you're quick about hitting the fullscreen button before it resizes. (In that case the behaviour is different -- we fail to change the size of the fullscreened window, so the openbios prompt isn't visible, and switching back out of fullscreen it's still just a plain yellow screen.) http://people.linaro.org/~peter.maydell/vexpress-3.8.tgz is a guest image which should demonstrate this, I think. >> Another oddity: on fullscreening, the window's titlebar remains >> visible, up until the point where the guest changes its screen >> resolution, at which point it disappears.

I didn't mean the menubar (which does disappear); I meant the title bar.

If you have access to a Lion-or-later version that would definitely be helpful. thanks -- PMM
