When navigating the menus the GUI has slight graphical glitches. It only happens for split second and the picture comes good.
I doubled gpu memory to see if it had any impact but it didnt.
I just wanted to ask about this one to make sure it is not faulty gpu because it is new. The other thing I suspect could be power supply, I'm still waiting on back-order for official rpi4 power supply so I'm using my old one. There is no under power lighting bolt appearing which did sometime happen with old pi.
