The game menu appears without even press "esc" during in game every 32 seconds or more

Each time the game menu appears (An approximate range of every 32 seconds) that your pressures without the "esc" key or any other key that you have configured for the game menu, this annoying while playing because you can't play without being interrupted by the game menu.

(This bug appears with or without mods)
