I'm experiencing an issue with the Liquify tool in the latest Photoshop Beta (version 27.0.0 from sept 25th).
In the Liquify window, the Pressure setting for both the Pucker and Bloat tools is greyed out and stuck at a value of "1".
However, the tools behave as if the pressure is set much higher:
I tested this using a Macbook Pro M2, using the trackpad with "Stylus Pressure" not enabled and I have also tested this with a Wacom tablet and the "Stylus Pressure" option enabled, but it has no effect on the tool's intensity. The pressure remains uncontrollable.
