A few updates ago, the Paintbrush tool changed its default brush fill pattern from Solid Color to Horizontal. I'm not sure if it was on purpose or if it's a bug on my end (I did try reinstalling and removing all of my plugins, however, and it didn't fix it), but I find it horribly annoying that I can't just have a solid color immediately and instead get the (I assume rarely-used) Horizontal pattern. Is there any way to change it back from my end? Thanks.
