I don't know if this bug was previously reported by some one else.
The bug appears when you are in te start screen of the game and i think it also happens in the loading of a mach
And i don't know if some else can replicate it, but basically is that, with your keyboard, if you hold the TAB key the UI flickers or moves to the left and then after a few mili-seconds y returns to normal. If you hold it without release, the bug will repeat until you unpress the TAB key on the keyboard. if you do this and then quickly unpress the TAB key at the same time it moves to the left, i will stay like that. To return it to normal you just need to press TAB again.
I don't think its crucial but hope this report help others and the devs.
PS: Sorry for the bad English if you need some help don't hesitate to reply or send me a message and i will try to respond ASAP.
