This part, C6 is a “just in case” component which is good design practice to include, but as it turns out most power supplies still work OK without this part installed. Out of the box, R-Pi graphics don’t necessarily fill the whole screen. One suggested remedy to this, which has some positive feedback, is to adjust the USB bus speed. A logic analyser or a digital waveform viewer is a very useful tool to diagnose problems with the gpios. If the PI resets at that moment, it is an indication that the power supply isn’t able to deliver the full current your PI requires, but dips its output voltage below a minimum when loaded with the full current the PI needs. The wiki has a list of working SD cards.
