What could mutter do? When it receives the make-fullscreen request, it immediately responds with "ok, go fullscreen then". Then when it receives the unmake-fullscreen request, it immediately responds with "ok, go unfullscreen then". I have a patch which "compresses" GDK_WINDOW_STATE events by dropping any previous event to the same window while updating the "changed_mask". That seems to fix the issue to me (though it triggers another bug, which I suspect is in mutter, causing the window to not display any more, and then display with the wrong size). Another possible solution I intended to try is to only allow dispatching one wayland event at once before dispatching the internal GDK event queue, but this would have a lot larger impact on things.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
