Duckypad OLED went out suddenly (FW 0.20.1)

[Kaos9111]

I had a strange problem today:

While I was changing the profile several times (minus button), the display suddenly went off. the buttons still worked (plus, minus and the macro buttons).

I had restarted the duckypad several times using the reset button and the usb cable. - without success

I then checked the display cable. I also unplugged it and plugged it back in. - without success

I then flashed the frmware 0.20.1 again. without success

I thought the ducky pad was broken :(

So I flashed the firmware 0.20.0 and the display suddenly went back on. after the update to 0.20.1 everything is ok.

I have tried several times to reproduce the error, I have not succeeded.
