Im on windows 10 and using Krita version 5.2.1
Im struggling on what the issue with this was, ive tried even reinstalling Krita to see if the problem would be fix that way. The problem with me was that the brush works but the UI is not working correctly. Anytime i use the arrows on the side of the slider the UI of the slider would not go up or down on how big the brush size is. It would snap to what it was previously sometimes when i click and drag what i want the size to be.
The things to did to see what works is that when setting to the max it worked as max brush size, same thing as making it small. typing the max also worked and the arrows also work. What doesn’t work is the visual Indicator of what my brush size is when i change the brush size.
