Garrysmod Visuals Multihack

I mean the GMOD window, the one the game is in. It simply vanishes and only the taskbar icon remains

Yes im aware. In some recent update the cleaned alot of code and since then its like that. Its something related to texture shader, i didnt really figured it out. I highly suspect its a bug in the game

what you could do is either disable or remove the feature, or add a warning.
