Hi @Lulux , the load of Font's are made by Direct3DTexture8.
So it is basically an instantiation of directX8 on your machine. If the problem persists and you have not yet done the test on virtual machines (even within your system.) I advise you to downgrade DirectX8 and re-register even if it is done in another folder.
If the problem persists, analyze issues related to the resolution of your machine.
Persisting even more, I would then recommend you to encrypt a chat system via render texture instead of making use of the standard chat engine, this would allow you in DX8 to work u
