After updating from Krita 3.3 to 4.1.1 the slider bar (it's on the back of the cintiq next to the buttons) on my Wacom Cintiq 22HD no longer works. It used to control my zooming in Krita, which worked amazingly for me. After updating, Krita doesn't respond to the slider in any way. Does anyone know if I might have my settings wrong or if it's a problem that's being worked on? I really miss zooming in that way and it is very bad for my workflow to try and learn a new way of zooming in and out.

Many thanks!
