Flickering LCD & errors on console (Prusa MK2S and Repetier Server Pro v0.92)

Before updating to 0.92, I had no issues with two Prusa MK2S connected to a single Repetier Server running on RPi. Now, one of them has continuous errors and a flickering screen when connected to the server. If I unplug the USB cable, the display goes back to stable. 

Any ideas about how to fix this?

    Nevermind...I think I got it. The one that was flickering was on an older firmware (3.1). I just flashed it up to 3.2.3, and the flickering seems to have cleared up.
