how to change comparaison mode / not in full screen mode

I’m on PL7 (PC version) and when i want to compare the original and worked out picture, not being in full screen mode, i can only see both pictures side by side. When I’m in full screen mode, i can choose side by side or with the slider. I’d like to have the slider mode (not side by side) without being in full screen mode. Is that possible and what shall i do to get there?

when in comparaison mode (not full screen) I don’t see how to switch from “side by side” to “slider” mode (as when I’m in full screen mode → then i have the dedicated button for it)

thanks for your support.

You may have a look here … and further down.

The “slider” mode is only available in full-screen mode in the windows version. Not sure about the Mac version
