Oh, I didn't noticed the change ; btw , not suprising because I also 
open less an less Krita since weeks because of a issue I'm affected with 
calibration ( https://bugs.kde.org/show_bug.cgi?id=277201  ) it happen 
with the Cintiq I have since half June and it's annoying to have the 
center of the brush having an offset to the stylus calibrated 
position... weird feeling while painting. If you have ideas how to solve 
it, pls answer the bug report and thanks in advance.
