Yesterday, I was messing around with the F5 and brush settings, trying to test if I could add PS brushes into Krita. Once I got the hang of it, I exited out.

Today, I'm just painting using the default brush and switched over to the bristles hairy brush and realized that I can't change its size to be smaller or bigger.

I'm wondering if there's a way to solve this or somehow reset the brushes' default settings. Thanks!

Hi shinorin,

I don't know what is causing the problem but I guess it has something to do with this bug -> https://bugs.kde.org/show_bug.cgi?id=348097

check if there is a tag selected in the drop-down in the predefined brush tip section , if it is any other tag than "all" then change it back to "all" and check if you can change the size now.

I was having this issue too, thank you for the workaround!
