Texture displacement map in real-time I want to texture the displacement map and see the change in the viewport immediately.

I use the Displace Modifier.

I try Eevee and Cycles, in both cases, Blender doesn't update automatically viewport. I need to click any settings in Modifier Properties or Texture Properties. After that all ok.

Is possible to texture displacement map in real-time?
Not exactly realtime but hitting Tab twice (goes into edit and back) after a stroke of texture painting will update the geometry right away.
