Python 3 example

Fullscreen clutter application are unresponsive outside of uper left part of the screen (about quarter). The problem occurs often, but not always.

Attached script creates stage with 8 actors which change color on mouse move. In fullscreen mode often only half of actors can be highlighted.
Comment 1 Jonas Danielsson 2015-01-09 08:08:43 UTC 
Do you have a HIDPI monitor? I can reproduce this with CLUTTER_SCALE=2 but not without.

I am seeing similar issues in champlain, where we can't pan the map in the lower right quadrant. And I see that when I check the event->x/event->y I get max half the width and height.

See bug: https://bugzilla.gnome.org/show_bug.cgi?id=733826
Comment 2 Jonas Danielsson 2015-01-09 08:09:17 UTC 
Although I removed the call to fullscreen before I reproduced it.

Do not CLAMP to width/height before applying the scale factor
we will lose all information we need to scale properly.

The above patch fixes the issue in Maps for me, when using GDK_SCALE=2 and CLUTTER_SCALE=2
