Dialog-box highlighting effect in Ventura
I recently installed Ventura, and am having a problem with the effect where, when a dialog box is open, the background, including all other open windows are greyed-out slightly. It's not unattractive in most situations, but I use software that uses a dialog box to make color and level adjustments to images, and this effect makes it difficult to see the results of the changes you are making. I've included a couple of screenshots to illustrate.
Does anyone know how to disable this effect?
