Difficulty using sidebar scrollbar with mouse



We’ve noticed issues operating the channel sidebar scroll bar using the mouse.

Steps to reproduce

Issue is occuring with version 4.1.2 of the Mattermost desktop application on Windows 10

  1. Have enough channels/DMs to require a scrollbar
  2. Try to grab the scrollbar by holding the left mouse button and dragging

Expected behavior

Sidebar will scroll up and down as the mouse is moved up/down.

Observed behavior

Mouse is unable to grab the scrollbar. Click target appears very small, as we’ve succeeded to grab it a few times, but most times we do not succeed. Scrolling with mouse wheel works as expected without issue.


Hi @jomaxro, thank you for reporting this.

I agree that the scroll bar is quite “thin” - do you see the same issue on the right hand side? What server version are you using? Are you on 100% zoom level?

This is most likely a UX issue, so I can forward the feedback to our UX team first.


We do not, no. Using the mouse to grab the scrollbar to the right of the messages works fine. The issue seems specific to the channel/DM sidebar.

Server version is 5.4. Zoom is 100%


Hi @jomaxro, our product managers agree with the feedback and our UX team has taken a note of making some improvements to the scroll bar.


Hi, everyone.

Just had this tested with Windows 10 with the latest client and we can see that the the size of the scrollbar between the chat history section and the list of channels are different.

Perhaps we can make them a little bit bigger and of equal size as well to make the UX better.
