Key for opening chat & whisper write itself sometimes

Thank you!

The slash is typed twice too!

Yeah right, I actually even forgot there was a key to open chat commands directly and it enters the key after the / too.

The console doesn't have this problem, know that's not supposed to be the same screen but hopefully this can help to solve out that chat bug. Also I think it's just a problem with the game updating time or something because whenever I'm having freezes (which is quite frequent with my pc), I'm really never having this problem, that's rather strange but I didn't look it up.
I still really hope this gets solved because it's annoying realising there's a random letter in the big wall of text I write sometimes, don't really want to delete it from so far.
