Yet another message… When I alt-tab back in the game, after having written you my previous post, the in game screen (deployment screen) was weird… I had all the background, but the foreground (text, blue overlay, icons, …), all of it was not shown anymore.
The mouse though still reacted to my inputs, transforming into a hand when hovering where the previous icon of a ship was before alt - tab.
I couldn’t resolve the issue, and had to exit with an alt f4 (since all the rest was gone). Also a press on escape didn’t brought me anything…
