Hostname when mouseover username in LAN Lobby only shows first letter for host

[penfriendz]

This only occurs for the player in the first slot, not for players in other slots.

Is this 100% with any user name? Or does the user name need to contain non-ascii characters?

The issue sometimes occurs consistently – only the first letter of the username appears for all players, both in all the slots and in the game list. The problem is not limited to the first slot; it happens in all of them.
