As reported by a user: is there a "way to change the 'sensitivity' of how quickly brush size changes using shift-drag(with pen on tablet) but right now I have to move the pen across the entire tablet over and over and over to make it smaller"?
Keyboard shortcuts are unaffected, but there does appear to be some odd scaling effect going on in Gemini. More comments by a Gemini user here: http://steamcommunity.com/app/280680/discussions/1/558752451483599287/
I noticed this when painting a bit last night as well.
A user reports that Gemini works fine with older images created in Krita Desktop - suggests it might be related to the crazy default resolution setting (though maybe this indicates that we might be doing something odd when it comes to scaling the brushes?)
