It seems GtkVideo assumes square pixels here, while this particular video has a pixel aspect ratio of 9/16.

FWIW, Tuba built with experimental Clapper backend does not have this issue.

Noticed that too but didn't know the exact issue, thanks! I can probably forward this upstream now since players like 'Light Video' are also impacted
