HUD goes off the screen in fullscreen mode on non-16:9 monitors

If you fullscreen on a non-16:9 monitor, for example, the (16:10, 2880x1800, though the game treats it as 1440x900) internal display of a MacBook Pro, the main background and text letterboxes as you would expect, however the HUD (part which supplies buttons for quick save, quick load, menu, log, skip, and auto) positions itself as if the game had been zoomed in to fill the display, putting the four right-edge buttons (menu, log, skip, auto) completely offscreen. Watanagashi is the first game I noticed this on (since it's the first game I played patched) but I would guess it also happens on the other games.

The issue describes a UI layout problem in fullscreen mode on non-16:9 monitors. Look for HUD positioning code, likely in a UI or rendering module. Check how screen dimensions are handled during fullscreen transitions. Test changes by running the game in fullscreen on a non-16:9 display or simulating the resolution.
