Slack Desktop Client Lags When Switching Between Conversations

The Slack PC client exhibits noticeable lag when users switch between channels or DMs during high-activity periods, breaking the fast-scanning flow that knowledge workers rely on. The performance degradation is particularly disruptive during busy project phases when quick context-switching is critical. This points to rendering or state management inefficiency in the desktop client.

Slack Thread Reply UI Makes Multi-Party Conversations Hard to Follow

Users find Slack thread replies difficult to navigate, with the interface failing to make the reply flow intuitive when multiple people are involved in a threaded conversation.
