Known issues

  • The following are the supported protocol handlers:

    • webexteams:

    • ciscospark:

    • webex:

  • The Webex App for Linux is not supported in Webex for Government.

  • Tile-based window managers are not supported by Webex App.

    With i3 window manager installed or other tiled window managers, you can experience some odd behavior with the reply or edit message windows. Such as windows intermittently disappearing, windows not positioned correctly on screen, windows may appear floating on top of the app.

    You can apply some workarounds to prevent the windows disappearing:

    • For i3 window managers, in the i3-msg config file set "focus_follows_mouse no". This will apply to focus on all apps.
    • For KDE, in the KDE 3.5 Control Center, select Desktop > Window Behavior, click Advanced tab, and un-check Hide utility windows for inactive applications.

  • Currently only 16-bit depth audio input is supported. Microphones with 24-bit sampling aren't expected to be compatible.

  • Users on tiling window managers, such as i3, may experience focus issues when trying to search. It may require several mouse clicks into the search box to regain focus after typing.

  • Configuring proxies using KDE System Settings is not currently supported.

  • Changing scaling using fractional scaling in the system settings isn't supported.

  • To use EPOS headsets with Webex App for Linux, RedHat users must do the following:

    1. Download the latest webex.rpm version of Webex App

    2. Uninstall the previous version

    3. Use administrator privileges (sudo command) to reinstall the new version of the app

X11 limitations when sharing your screen or application

  • When you share certain applications, such as Google Chrome, the red border displays a shadow effect around the application window.

  • You're unable to change your system display settings while sharing your screen or application.

  • The resolution of the area you're sharing must be less than or equal to 4096 x 4096 p, regardless of what you're sharing.

If you subscribe to Webex from your Service Provider, your meetings in Webex App are always full-featured.

Over the next few months, Webex is enhancing the meeting platform to Webex Suite meeting platform. This platform improves and simplifies hybrid work across the entire Webex Suite, and incorporates AI-based experiences, with common architecture, administration, and integrations.

The platform formerly known as the Video Mesh-ready meeting platform is now called the Webex Suite meeting platform.

The new platform converges the meeting experience across Webex applications and devices, and delivers continuous collaboration before, during, and after the meeting.

To check if you are on this new platform and read about key changes, new, and forthcoming features, see more about the Webex Suite meeting platform.
