i have display connected pi , need power battery pack.
gpio power pins connected have been powering through power connector on pi. reading on here understand should powering through power connector on display board. tried same result.
seems work fine either way getting "rainbow box" appearing off , on.
battery pack has 2 usb connectors thinking disconnect gpio power pins , power both display , pi via power connectors independently.
should independent power work?
how big of problem have "rainbow box" come , go?

without encouragement here went ahead , tried separate power connections. works.
since battery pack have has 2 usb ports assumed have common ground. disconnected both power interconnect wires between pi , display. connected each of boards own usb port on battery pack.
works fine , not "rainbow box" during normal operations.
