I use Ableset both on my PC and my macbook Air. I use jpg and png files to display full screen with the [full] text in the Lyrics track. It works fine on the PC, but I don’t get the full screen for pictures on my Macbook Air. I don’t know if I am doing something wrong. It is the same Ableton file.
Macbook Ableton version 11.3.20
Ableset version 2.6.0 beta 6 on Macbook
