Steps to reproduce: On a Mac with an external monitor (this is an M1 Macbook Air plugged through a hub into a 4k display over HDMI), launch the game. Go into Settings -> Graphics and change the resolution. Enter any match. Leave the match by winning or conceding.

Platform: Steam on MacOS 26. Game version 2026.55.0.4094.1225076.

Actual results: The resolution resets itself to the default (5120x2880) whenever the game changes scenes, ie entering or leaving a duel. It also resets when quitting and re-launching the game.

Expected results: The resolution setting, once set, stays the same across scenes and game launches.

Other notes: On this specific machine, the game does not run at an acceptable framerate at maximum resolution, but it runs just fine at 1440p. This bug makes it necessary to constantly go into settings and adjust the rendering resolution.

Please note this seems distinct from other resolution/fullscreen bugs other Mac users have reported, probably because I'm using an external monitor with a 16:9 aspect ratio. The game launches in fullscreen and displays correctly, it just renders at a resolution that's too high to run at an acceptable framerate; but once the resolution setting is adjusted, it runs fine.
