So I contemplated this. Not sure what the difference in screens is, but let's say I really loved the WRX and wanted to keep it and it was just ONE screen bothering me - I'd absolutely source that screen from a 2019 model and swap them.
Where it's ALL the screens as well as the dials, I suspect there is some inverter that is shitty, or else the entire thing is driven by bad current, or … something.
