Hey @ExaBast,
The easiest solution to this would be turning off Origin In Game to prevent this from occurring in the future. This can be done by clicking Origin in the top left hand corner of the Origin client, selecting Application Settings, and clicking on the Origin In Game tab on the left. From there just, make sure the check box is clear.
If you're hoping to keep it enabled, I'd start with ensuring your in game resolution matches your desktop resolution. If that is the case or you're still experiencing the issue, let me know and I can see what other solutions I might be able to come up with.
