[Bug]: The game's maximum resolution is reduced when using scaling on a 4K display

[PerAstraAdDeum]

Describe the bug

When using scaling on a 4K display, the maximum resolution in games launched by Bottles is reduced. For instance, when using 150% scaling on a 4K display, the maximum resolution available on Witcher 1 (GOG) and Crysis 1 (GOG) is 1560x1440. When scaling is set to 175%, the maximum resolution of the game is 2194x1234.

OS: Arch Linux
DE: KDE Plasma 6
Display: Philips 279M1RV
GPU: Intel Arc Graphics iGPU

To Reproduce

1. Open your DE's display settings and set scaling to any value above the native 100%.
2. Open bottles, start a game of your choice
3. Try to set the game's resolution to the one native to your display. Now you'll notice that the maximum resolution is reduced by a factor correlated to the scaling factor, e.g. maximum resolution in Crysis 1 (GOG) is 2560x1440 when scaling factor is set to 150% on a 4K display.
