Global Chat messages causing micro stutter

Messages and item links in global chat cause CPU frametime spikes (30ms+) and stuttering. Restarting the game fixes it but it will come back eventually.

Persists, and this is not limited to only global chat but also trade chat, basically any new messages sent by other players causes these stutters consistently. Just turning off "Show Global Chat" or "Show Trade Chat", has no effect, it only hides the chat for me, but players messages still pass through and causes the same stutters.

Only reliable suggestion is to manually go to a dead channel, for example /global 999, or /trade 999 fixes the stutters completely as there are no players in these channels and hence no messages.

This is extremely bad, as it forces players away from social interaction, and if they aren't aware of this, it causes an underwhelming combat experience with the stutters. Worse is, this probably also occurs with other chats like whispers, parties, and guild chat.
