Overview
Old School RuneScape fills whatever window size you give it once 'Game client expands to fill the window' (resizable mode) is on, so 21:9 and 32:9 work. The UI panels sit in the screen corners, so on very wide screens they end up far apart.

Verified via PCGamingWiki (ultrawide true, resizable client option). Edge-anchored UI is based on the resizable layout design; sourcing beyond PCGamingWiki is thin.
