Good Afternoon,
I've recently been trying to use Affinity Designer after the 1.9 update but came across some kind of bug. When in the Designer Persona, all brush models are clearly seen and can be used. When transferring to the Pixel Persona on the other hand, all brushes turn invisible and cannot be used. I have tried using the "Clear User Data" dialog by holding 'Ctrl' but it still has not solved my issue. Here are photos to help anyone out.
