Photoshop 21.1: Brush cursor preview doesn't show the state of the pen

The brushes all work as intended now. But there is a new issue: the brush cursor preview doesn't dynamically show the current pen position anymore. It's static and doesn't change shape or move at all until I start drawing onto the canvas, at which point it will snap to and remain in whatever state the stroke started with, up until you start a new stroke again and so on. This applies to all brushes, by the way, not only the legacy bristle tips, so arguably it's way worse now than ever. I understand that the live preview window in the top right has been removed recently, but this surely can't be part of that? It still worked in 21.0.3.
As before, reverting to 21.0.3 or 21.0.2 fixes the issue.



As you can see here, the brush tip cursor doesn't follow the actual rotation of the brush.
