When starting a print with the Mini 2 through the SD card reader, the LCD will freeze after a few minutes into the print. Also looses all functionality to the LCD as well, so you can't do anything until you restart the printer. Happens on (at least) both 9.10 and 9.11.

@nathan: Please try 1.1.9.12 and see if it helps.

@karrad It looks all good here now. No freezing through a 2 hour print. I'll also test this on the Micro and let you know how that goes.
@karrad Looks like the Micro is good too. Not as far into a print (going to be gone before this one finishes), but its working as it should.
We encountered something similar to this on the Mini 2 AS at IMTS. @MikeR should be able to pull the unit from the show pallet once it's delivered. The SDcard should still be in the GLCD.
LCD screen froze at 38%, print finished and LCD unfroze. Mini 2 running 1.1.9.16
Clarification: print was running through USB
Similar issue here, but earlier in a print. Just happened today. LCD unfroze once the print completed.
Still freezing on 1.1.9.17 Mini 2 Micro - USB printing - LCD unfroze upon print abort (didn't stick to bed)
I am using 1.1.9.28 on a mini 2 with a Hardened Steel Plus toolhead, connected via USB to Cura directly. My LCD froze, I restarted the machine to get use of it back.
