Crash on Screen Brightness or LCD power



  • Attempts to set display brightness to 0 immediately crashes the M5Stickc back to the UI flow screen. Attempts to set it to 1, then return the display brightness to 75, generates a streaky, difficult to read screen, and shortly afterwards also crashes to UI Flow screen.

    I then attempted to mimic the desired behavior using Set LCD voltage to block, and got a similar problem. Using 0 as the voltage generates an immediate crash. Using 1 seems to turn the screen off, but trying to turn it back on (using 3, or 3.3) left the screen streaky and distorted, and was again followed soon after by a crash.
