When I set the "alpha" to 0 so that the background is transparent, the rendering bug at the level of the mod name and it adds differents characters before the mod name (see the screen below).

Hello, you need to delete the config file to let it regenerate a new one.
This issue is fixed in 3.1.4

Perfect thanks!
