That might be a bug (we have similar issues with existing code), I will try to look at it. > 3) When making resolution changes from within the guest, > remote-viewer resizes then sends a resolution change event to > the guest, which can lead to getting another resolution then > requested.

There are 2 schools: 1. allow window resizing, in which case, the guest can reconfigure the window size any time (can lead to very large windows, or intermittent resizes etc.) 2. never resize client window automatically, and avoid scaling: the client will try to resize-guest whenever it doesn't fit well In general, the GNOME guideline follows 2: only the user is managing the windows size. However, I think we should improve the fullscreen case, and allow scaling when the guest change resolution. But it will be more difficult to deal with cases where user switches between window and fullscreen, as we will have to try to restore the same resolution somehow. -- Marc-André Lureau _______________________________________________ Spice-devel mailing list Spice-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/spice-devel
