Solved Retraorch square bug (can't solve)

[jthemad]

Hi all, I'm testing the last 4.1 unstable on rpi3 and I can't solve the 'retroarch square' bug.
I tried to remove the ~/configs/retroarch/retroarchcustom.cfg and Recalbox generates it again, I restarted the system but I have the same problem. I know other people solve this bug, could you please tel me the extact procedure? Thanks all and sorry for my english

Would this square?

If it is, this is a problem of under voltage
