Hello,

So this issue happened out of nowhere. As of today I now have a little black triangle in the top left corner of my screen, the size of a few pixels. Never occurred before, doesn't occur in any other steam game, app or on desktop, and zero dead pixels on my monitor. Happens in windowed mode too.

Zoom on the artifact :

I have a screenshot taken with steam from august 25, and here everything is fine.

Really don't know what happened here. I don't remember updating any drivers in that short time period.
Thank you for your help.

Edit : So this seem to only happen in gamemaster solo, in zeus or remote player mode, doesn't appear in multiplayer. However, in gm solo, if I create a spawn point and respawn normally the triangle disappears and doesn't come back until I return to the main menu and start a new game.
Happens in the tutorial too.

Edit again, I checked old screenshots and the bug was apparently present before, I just never noticed it. Always in game master solo, but sometimes it's not there too, weird.
