toribash 4.93.

Idk why this is happening over here

you mean the description of the servers? i think you should dl a later version. I myself, use 4.95

Probably due to the window size, make it wider.

I think the screen size didnt affect this cuz we all know that the word "Aikido" "Mushu" and "Judo" can fit in there.

Do this, Esc>Setup>Options>Window Width 1280>Window Height 720, that should fix it.

The chance that his screen is the exact same size as your isn't that big. If I'd set my height to 720 it would already be too big for my screen.

And as Science said, it probably has nothing to do with the size of his window, as there's plenty of room for 1 extra letter.

Try updating to 4.95 or 5.02.
Otherwise, try steam it's 5.02 with auto update.

The last letter always seems to get cut off for me too. When you make your own server, all you have to do is add a space after the last letter of the description.
