OSD Aspect Ratio is Wrong

Hi all,

I’ve been high and low and I can’t figure this out. I’m using a Pi3 with LibreElec, and I’ve been able to get everything to work correctly, except for one little issue–the OSD is in the wrong aspect ratio! I’m using it on a 4:3 LCD monitor, and everything else seems to be adjustable (and working), but the OSD continues to consist of squashed ovals rather than circles. Any thoughts?
