Really? I honestly have no idea what you're referring too, as someone that uses slack at a full time remote job. Nothing blinks or flashes as far as I'm aware.

Really? I honestly have no idea what you're referring too, as someone that uses slack at a full time remote job. Nothing blinks or flashes as far as I'm aware. Just the UI changing when other people interact with the server. Like emoji reactions pop in if someone adds one. Or left side bar highlighting things if there's new messages in them, etc. Things pretty much any other chat-like application does.
