Photoshop: Bristle Brush Pen Tilt Problem Upon App Focus Switch
Bristle brushes do not adjust to pen tilt after focus is shifted to another application. That is, the bristle brush engine works perfectly up until Photoshop loses focus, after which it will no longer adjust to the tilt of the pen. The 3D preview, cursor, and stroke appear completely unaffected by tilt. Only solution so far is to restart Photoshop.
