--- Comment #2 from Ralf Habacker <ralf.habacker at freenet.de> ---
Git commit fbfbffea75726b5a2d329a791c896dfb809bbfde by Ralf Habacker.
Committed on 26/01/2016 at 12:47.
Pushed by habacker into branch 'Applications/15.12'.

Fix wheel mouse inaccuracy on zooming.

The inaccuracy is caused by UMLApp instance and UMLView scroll bars
propagating slightly modified zoom value back to the UMLView instance.

The fix is to disable the back propagation.
