Overview
On a 32:9 panel, CK3's map/globe view extends reasonably well (hor+ camera), but the start-date/character-select screen crops portraits and the main menu and several UI panels are pillarboxed or cut off at the edges. Playable without mods but feels cramped on 5120x1440; the community 'Ultrawide 32:9 UI Fix' Workshop mod is the go-to for reclaiming that screen space. No Flawless Widescreen plugin exists and no official 32:9 support statement despite years of requests.

Working with fix
Map view is fine but needed the Ultrawide 32:9 UI Fix mod to stop diplomacy/character panels clipping off-screen.

Fully playable natively, though the main menu and start screen still show pillarboxing.
