I recently figured out how nice Wine works for running old Windows games. However, many of them are fixed at 800x600 or another similarly low resolution. No big deal under X11 or Windows since the game will just stretch to fill the screen. But on KDE Wayland, the game just runs unscaled with black bars all around and none of the display settings seem to help. Is there an accepted way of setting the screen to a lower resolution but stretching it to fit the full display on Wayland sessions?
Wine has always done that, last seen on Plasma 5 (I switched to Wayland with Plasma 6), and I remember that being a thing way back in 2007 too. Valved patched the scaling in Proton as well I believe so that might be why it didn’t do that.
It behaves how fullscreen apps work on Windows, takes over your whole display and messes with the resolution and all.
