Is that the energy saving mode turned off?

Hi guys, Im not new to the system, but i've recently bought an used xpro1. After the first shots i noticed that the camera, now and then, becomes quite slow and doesnt response quickly at all, especially when i click down, menu or the q button. So i have to press these buttons several times, before something happens. That only happens, when an af-lens is mounted. Without a lens, the camera works smoothly and doesnt lag at all. The lens is a viltrox 23mm f1. 4. Both the body and the lens are updated to the newest firmware. Does anybody have similar problems or an idea, how to fix this problem? Tried to do a hardreset, using and formatting different sd cards and playing around with the settings. Cheers
