I've been living with this stretched aspect ratio in OSP for years and finally decided to try to fix it.

I fired up quake3e, changed my resolutions around a few different ways with just vanilla q3 and noticed my reticle is seemingly round at 1920x1080. Yeah - Aspect ratio seems ok....

Fire up OSP and it's back to being stretched again. Am I doing something wrong? I'm pretty sure both q3config.cfgs have the same graphics settings. Running Linux btw if that matters at all.
