+Subject: [PATCH 1/1] randr: make RROutputChanged change the main protocol
+ screen not the gpu screen
+
+We only set changes on the main protocol screen as, for example
+in RRSetChanged() and RRTellChanged(), therefore we should follow
+the same logic when reporting that an output changed in
+RROutputChanged().
+
+This means that RRTellChanged() will then update the relevant
+timestamps also when events come from gpu screens.
