P: No red preview when changing brush size

Could you tell me how do it? I’ve never did a downgrade until now 

Same. I just went back to the previous version and will wait until Adobe fixes the issue.

A mí me ocurre lo mismo. Tengo w10 actualizado a la última versión también.

I tried to restart all the preferences form start but nothing happen 😕😕

I have the same issue on a Windows machine.

Desde la última actualización ha desaparecido la previsualización del pincel (Rojo) que permitía ver la dureza del pincel. Además han desaparecido los pinceles mezcladores que tenía.

Same here, impossible to paint, Blinded Art from now on until Adobe solve this issue.

I hope that issue has nothing to do with "Brush preview windows doesn't display" as its discontinued from now on

Same issue here. Running Windows 10 with GPU enabled.

same for me. hope it will be fixed soon

Same Problem with new update
