Menu Flickering - Saving Game is based on Luck

[theAkito]

Wanted to try out this gem. When opened & starting a new session, the game menu, after pressing ESC, flickers and then disappears. Pressing any menu button is a matter of luck. If I spam left-click an entry it might open or not.
Therefore, there is currently no reliable way of saving the game or doing anything else in the in-game menu.

Tested on Windows 10 with the currently most recent release.
