on latest 1.18 version, when game loads for first time and GUI scale is at auto, you cannot press the "apply" button due to the tooltip popups interfering by overlaying with it.

I can confirm this, it's impossible to change GUI scale.

Hello, I have made a temporary hot fix for it. Can you guys try this build out? https://github.com/FlashyReese/reeses-sodium-options/suites/4625694998/artifacts/125217607

Yep that one works good

Fixed in c6bb5b9. You can try the latest release.
