Happens to me too (Windows 10) and isn't limited to Slack, but all the services. I can CTRL-0 to reset the zoom, but the CTRL- and CTRL+ do nothing. Trying the Zoom In/Out from the View menu does nothing either.

It used to work, but not now. Version 5.4.0-beta-3.

Update: Just installed the full 5.4.0 release and the problem persists.

As a fix in the meantime, View -> Toggle Developer Tools and execute this Javascript in the console:

const webviews = document.getElementsByTagName('webview');
for (let e of webviews) {
  e.setZoomLevel(2);
}

Where 2 is the zoom level you want.
