The three typing dots stay still instead of pulsing, so they no longer redraw every frame.
Covers every place Discord draws them: the typing indicator above the chat input, typing on forum posts, the typing status on avatars in your DMs, and typing in the channel list where Discord shows it.
The dots drawn by Channel Typing Indicators and Discord's emoji or animated custom typing indicators are not Discord's typing dots, so they keep moving.
The still dots look like the ones Discord shows when Reduce Motion is on. With Reduce Motion already on, nothing changes.
A port of Vencord's NoTypingAnimation.
Settings
None. Turn the plugin off and the dots animate again.
