Vertical ad screen with Coca-Cola's Christmas ad featuring Santa's sleigh and a winding trail. The video runs at about 20 fps and there are obvious vertical tears in it. Also featuring rolling shutter and moiré artifacts not seen IRL.

vsync and double buffering should help. this display is probably rotated 90 degrees

Definitely. Yes, most displays this size are natively horizontal. Also, the low framerate suggests the SBC was not made to play 4K video, they should decrease it to 1080p for video ads or replace the whole thing if the memory bus turns out to be too slow to handle overdrawing the framebuffer in 1/30 s.
