webkitgtk isn't just quirky, it's also much slower compared to more popular browser engines and is particularly bad with RAM usage.
I remember encountering one bug with Final Form that triggered rarely in Safari, 100% in Webkitgtk, and never in Chromium.
Here's the developer of Tauri saying it's hard to recommend webkitgtk / Linux support:
> So if you need good linux support now/soon i can't 100% recommend tauri (for Linux) as of now. (I used to be more "forgiving" but with webkitgtk getting worse/more unstable each release i changed my mind)
