In fullscreen it looks exactly the same, only the black border is even greater. If it helps, I'm using a Firefox browser with Windows 10, hardware acceleration on, opengl rendering. The game reports nothing unusual. If you are using Godot 4.3, try disabling SharedArrayBufferSupport, it may help!

Nope! Disabling sharedarray also let you embed your game into the itch window instead of popping it out in a separate window for firefox users.
