Mumble provides a native "Overlay" that allows you to see who is talking, while in-game. You can choose the font, location on the screen, size, colors, and even custom textures for each user.

User Textures

To create a custom user texture, just create a 600x60 image (we recommend a 24-bit PNG with transparency) and go to Server -> Change Texture in the Mumble client. You can set that image to your texture, and other people will see it when you talk, rather than your name.


Mumble allows you a wide rage of control over the overlay, including exact positioning, deciding what you want to show (show everyone, show only people who are talking, etc), colors, direction that the list grows in, etc.

Incompatible games

From the official Mumble wiki:

Games with Major Issues

  • Combat Arms (overlay causes game to crash after map changes; overlay will not display unless one joins a server and then leaves it)
  • Supreme Commander (Only in multiplayer)
  • Vanguard (crashes to desktop when overlay is enabled)

Games that are known to have minor issues with the Mumble overlay:

  • Any of the "Dawn of War" series (overlay will not display)
  • Warcraft 3 (overlay will not display)
  • Killing Floor and Red Orchestra (same game engine; the game will crash when changing resolutions or going into fullscreen mode)

Disable Overlay for a particular game

If you would like to disable the overlay for a certain game (because you do not want it in that particular game, or that game has issues with the overlay), and do not want to disable the overlay altogether, put a file named nooverlay (without any extensions) in the same folder as the game executable is located. This will tell Mumble that you do not want the overlay in this particular game.
