This happens for example for Way to Go! Steam game and perhaps any SDL 1 game. It's easy to reproduce, install a game using SDL 1 library for example abe (apt install abe) and try to run it. There are two kinds of effect, the abe and perhaps other games from Ubuntu repository fails to run properly fullscreen only on first use after login. On second and further run they launch properly on fullscreen. The Steam game (Way to Go !) fails to run fullscreen each time. Sometimes you see only part of the game screen at top left window and you even can't operate it, sometimes whole screen is shown. When you manage to reach game settings switching fullscreen on and off few times makes the fullscreen run properly. The problem doesn't exist for example using Unity or Windowmaker sessions. It exists using any Gnome 3 Xorg sessions, even the classic one.
