Maybe it's part of some kind graphics overlay which is getting shown by error in certain situtions...
That thought went through my mind. Although not with the current pixel cluster its far right bottom of the screen and 'ragged'
When I checked online couple of users reporting what look to be the same issue. One person noted, the pixel disappeared when the mouse cursor went over it. Another complained of a red pixel appearing dead centre in the screen.
I got that when I first fired up the monitor. Red dot centre screen, when I fired up a game, it moved with the cursor. At first I thought I must have hit one of the crosshair cheats in the o.s.d but I had not altered anything, never use the gaming cheat stuff: whatever it was dissapeared never to return. Juist put it down to a weird random glitch and forgot about it.
Who knows, odd rag bag of glitches, some software, some possibly hardware or simply driver imaturity. Probably not all related. Worst issue is gone for the moment, if it returns test with different system and card, hopefully narrow things down.
But for the moment, g.p.u driver clean up seems to have worked. So hopefully a resovable software issue.
Immposible to work out cause from correlation, its happened twice now, each time imediatly after firing up a fresh install of an ubi soft game. Ghost recon last, Assasins creed valhalla first time it happened.
Almost certainly chance but who knows? Does seem to be consistant and software related, so if it occurs again, should have a better idea what is going on.
