Firmware 3.13.1 Issues - Blank Screen and then filled with unknown characters

After upgrading my Original Prusa i3 MK3S From FW version 3.9.3-3556 to version 3.13.1-6876, my screen sometimes goes blank and I have to press ESC to exit and the print reset. Other times the screen gets funny characters like the attached pictures.

My  printer was working Ok until I upgraded.
Please any help will be appreciated 

thanks

Carlos Delgado

RE: Firmware 3.13.1 Issues - Blank Screen and then filled with unknown characters

I am also having the blank screen issues.   Noticed it recently.   Also on 3.13.1 recently.   I haven't see the unknown characters.   It recently happened when turning on the printer and going for a filament change.   Around the time the printer heated up and I clicked the knob for extracting the filament.   The screen went blank

As I spun or clicked the knob the screen would intermittently flash and some characters were momentarily visible.   At some point a short minute or so later the screen comes back up as normal.   

It may be unrelated but the center of my screen seems to have a bit of a hot spot where several of the pixels in the center are partially brighter than the others blue ones around them.   Maybe I"ll adjust brightness.    Maybe the screen is going out.  But it's very curious that it follows the FW upgrade and @CarlosD is having a similar issue.
