Bug Report

When I try to start a new chat containing more than a couple of hundreds of lines, the browser freezes for several seconds before actually sending the request to the backend.

  • I am on the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • I have provided the exact steps to reproduce the bug in the "Steps to Reproduce" section below.

Expected Behavior:

The experience should be smooth and the request should be sent immediately.

Actual Behavior:

The browser hangs for several seconds before sending the request.
