When selecting the multibrush tool for the first time after starting krita, it mirrors both horizontally and vertically, even though only the "horizontal" checkbox is selected. After checking and then un-checking the vertical checkbox, it stops to mirror horizontally. Reproducible: Always
I can confirm this bug. Steps to Reproduce: 1. reset your Krita configs 2. restart Krita and select the tool "Multibrush Tool" 3. go in "Tool options" > choose "Mirror" from the dropdown menu > check "Horizontal" and start painting Actual Result: "Multibrush Tool" ignores the checkboxes for Horizontal and Vertical in the "Mirror" mode, when used for the first time. (Ubuntu 14.04 Unity - Krita 2.9.1 (git 60518b7))
