I can confirm Karls findings. The slowdown of 1.1.3 is quite obvious when, for example, using the interface plugin 'floating window' http://interface.eyecon.ro/demos/windows.html http://interface.eyecon.ro/demos/windows.html . On minimizing/maximising this window disturbing visual animation artefacts occur with 1.1.3 . Transitions are pretty smooth however with 1.1.2
