My screen tends to flicker as i play and it sometimes gets so bad that it covers my entire screen,it did this with servers and the server screen but today it started on survival worlds as well. Also since ive started playing whe i press f3 i dont reccive cords which is hard to play without cords on servers these are my problems i have on minecrarft. the screen flicker also effects the items in my invy. In the picture shows no cords and my invy flickering.
