Hello there,
I have been experiencing issues with my Paint Brush tool. I purchased Affinity Photo a couple months ago and installed it on both my iMac (late2015) and MacBook Pro (late2012).
Everything has been working with no problem until last week when I opened a project on my iMac. I was trying to mask a layer, I press B and the Painting Brush was a SQUARE instead of a CIRCLE. It started acting weird. I don't know why. I don't have that issue on my MacBook. Everything works fine. I tried uninstalled it and installed it back and still had the same issue.
Please help.
I attached two pictures.
