Schematic of the suspect pin I mentioned.

Answering the question about the viewfinder: because it’s much more natural and convenient to aim, in particular if you must do it quickly. The camera follows directly your head, so it works just the same as you would want to look at something. With an external display there is no natural synchronization between what your brain wants to look at and what your hands do. This is why all DSLRs still have a viewfinder, even if nowadays it’s sometimes an electronic display which offers quality no better than the external one. The same goes for many professional camcorders, unless they are so big that your head basically fits the back of the device or at least moves in-line with the camcorder

That was also my first guess when I saw the display rolling, V-sync signal missing. Knackered display flex PCB or slightly misaligned in the connector.
