Well I did do a reset system settings in the ffxiv launcher. But I don't know if something happened when I pressed the reset button as I didn't get any notification that something happened. I also downloaded then my ingame settings in anticipation that something would have changed. Although I opened the game after a full day since the reset. Since that day, it didn't happen yet.
I already read in some forums that certain programs like teamviewer or discord can give ff14 some issues. I still don't believe that even one of those programs are the culprit since I don't have the discord overlay on or even have teamviewer on my laptop installed.
