I’ve added a button with the Liquify menu item from the bottom SliedIn, so that I can have a button to open the Liquify window quickly.
What happens is this: the window opens but, before I touch anything, there is already a displacement done on the right half of the image. It’s easily viewable by activating/deactivating the preview tick box.
I’ve made sure that it was the right menu item and compared with opening with the keyboard shortcut, where everything is normal (no displacement upon opening the Liquify window).
There is definitely a displacement coming from opening the Liquify window from the button on Configurator Reloaded version 1.9 in Photoshop 2020 and 2021.
