All Steam games have this small black square. When I look up the issue it appears in this 7 year old Reddit thread. Oddly.

Why would this bug, or a bug similar to this appear again.
Steps for reproducing this issue:

  1. Open some games. The games I encountered with this issue was TF2, Garry's Mod, Half-Life, and Postal
  2. A small black square is there. For whatever reason it doesn't appear on MGSV.

Note: after more testing games.
Notably a Source Mod in Proton, and Hitman WOA don't have this bug. This bug seems to only happen on Linux-native games, and not proton games.
