Long answer: that's because i changed an option in winecfg that keeps the opengl application on top no matter alt+tab or ctrl+f2 that i can't tell you exactly if i get this bug or not. I am dual booting and a little busy so I think that I'll reboot this evening or tomorrow and i'll hope to fix this, so i will let you know.
Short answer: i don't know.
