Checklist

I have searched for a similar issue in this repository and did not find one.
I am using an official build obtained from releases or updated one of those builds using its in-app updater.

Describe the Bug

I am attempting to use a minimal config.toml that only contains the settings that I need changed from the defaults, rather than the entire auto-generated config. When I do this, shadps4 crashes immediately upon launch. I have narrowed it down to the geometry_* settings.

Reproduction Steps

Launch shadps4 with no config.toml to populate config.toml with the auto-generated defaults. Then close shadps4.
Open ~/.local/share/shadPS4/config.toml. Under the [GUI] section, delete the lines for geometry_(h|w|x|y).
Launch shadps4 again.

You will get: floating point exception (core dumped) shadps4 and shadps4 fails to launch.

Expected Behavior

When settings are omitted from config.toml, shadps4 should use the same default values that would be written to the auto-generated config.toml. This way, when we encode our configs into our gitops setups (ansible, nix, or just committing your configs to a git repo), we can write only the settings that we've changed rather than including the full auto-generated config containing transient settings like window geometry.

The crash should be fixed now, since missing config.toml settings are regenerated on emulator startup.
Please let me know if this crash still occurs, and I will reopen the issue.
