After the updating to 0.12.1, every time that i open a furnace to use it, a part of the screen is blinking. This happens to all the screen, except its banner which contains the title "Furnace".
The screen gets black for some miliseconds and this happens continiously with a periodic pattern. Once I exit from the furnace's screen, everything is normal.
