Symptoms

When running MiSide (v0.93L) on Linux via Proton under Wayland, the 1920x1080 resolution option is missing from the settings menu.

While the game may default to 1080p on the first launch, once the resolution is changed to any other value, it becomes impossible to select 1080p again through the UI, as the option disappears from the list. This issue has been reproduced on both NVIDIA and AMD hardware:

Device 1: Kubuntu 25.10, RTX 5070 (Proprietary Driver 580.95.05)
Device 2: Debian 13, Radeon Graphics (Mesa 25.0.7-2)

Currently, the only way to restore 1920x1080 is through a manual registry edit.

Reproduction

Launch the game on a Linux (Wayland) environment using Proton 10.0-3.
Navigate to Settings > Graphics > Resolution.
Observe that 1920x1080 is absent from the resolution list.
Change the resolution to any other available value (e.g., 1280x800).
Attempt to revert to 1920x1080; the option remains unavailable.
