The X server sends several RRScreenChangeNotify events in a burst when something happens which, currently, causes us to rebuild our view of the world as many times and notify the upper layers about it which causes a lot of bogus repeated work like rebuilding background actors. We can avoid this extra work by looking at the timestamp in the XRRScreenResources struct which is updated when an X client (including us!) last changed something and comparing it with the previous timestamp. https://bugzilla.gnome.org/show_bug.cgi?id=738630 |
