HIDPI scaling can make the game run larger than the screen size on some monitors.
The WINIT_X11_SCALE_FACTOR environment variable overrides the HIDPI scaling factor.
For example:
WINIT_X11_SCALE_FACTOR=3 cargo run --manifest-path wgpu/Cargo.toml
To set up a shell with an installation of rust and external dependencies:
