Overview
Stellaris renders the galaxy map correctly Hor+ at 21:9, but on a 32:9 panel the built-in UI doesn't stretch far enough — event windows, the outliner, and situation logs stay clustered near the center-left, leaving dead space on the sides. The old dedicated Super-Ultra-Wide workshop mod is abandoned and now crashes the game. UI Overhaul Dynamic is actively maintained and gives modest wide-screen adaptations, but doesn't fully solve 32:9 layout.

Working
Galaxy view expands fine, but event popups and side panels leave a lot of unused space.

Working with fix
UI Overhaul Dynamic helps somewhat but panels are still bunched toward the center.
