Brush doesn't show up in brushes and shows 4 lines in each corner of brushe when trying to use.
I'm using 2.10.12 on windows 10 and am having problems with the brush showing up in brushes and being able to use it. I use gimp a lot and would say I know how to use the program. I'm thinking it's definetly a bug. Never had the problem before, and I've made a lot of brushes.
