Logitech keyboard applet text garbled [Client] [7.14]

Same as this bug on the euw forum. The Logitech keyboard applet started displaying garbled when the update to 7.14 happened. I only have screenshots with the emulator, which can be used through the Logitech software, but it shows up exactly the same on the actual keyboard.

To reproduce, start a game with a Logitech G510 or similar Logitech keyboard with a screen. Update to the current client and start a game.

This error happens 10/10 times just like this.
