Star Pattern graphical glitch

I sometimes get a flashing star pattern going berserk out from my crosshair to the edges to my screen. It lasts a few seconds then goes away again. Its not my graphics card because I sometimes can see this when I am dead and spectating the spawn camera of squadmates, then the star pattern is only in the small video feed on the bottom right... Anyone else had this? I am running 4k DLSS Quality, Settings are Ultra except Texture Quality,  Texture filtering and local light and shadows on overkill, Volumetric Quality and sun shadows at high. SSGI Low. I tried to change to GTAO High but I encounter the strange graphical glitch there aswell.
