Hardware tests online
Something feels off with your hardware. Test it now.
Your mouse double-clicks on its own. Your gamepad drifts. Your mic crackles. Pick the device that is misbehaving and run a browser-local test that separates a real fault from a settings or setup issue — before you buy a replacement you may not need.
