Don’t worry, you’re not missing out on much, running video games, or any OpenGL thing including 2D games and GPU-accelerated terminal emulators is a bad experience, and alt+f4 isn’t implemented, and f11 to fullscreen is janky, and theming for buttons and such is clearly alpha.
The promise of an Arabic-supporting, Rust based, GPU-accelerated terminal is too attractive, however, as I was teared between multilingual terminal, Wezterm, Alacritty and Kitty for a while.
The first is horrible at everything but supporting languages, the second is really janky, the third doesn’t support tabs, the fourth has bad theming and customization.
