In the settings of my Wallpaper Engine it is configured that the program pauses the background animation when opening applications, thanks to it I realized that when minimizing one of the tabs of the group, only it minimizes itself, and the rest for the system remain unfolded, as a result, the Wallpaper Engine animation still does not work. To fix this, I have to run through all tabs with Alt+Tab and hide them manually to make the animation work again.
Dear developers, can you fix this in the new version and make it so that the operating system hides all tabs at once?
