## This script is used to launch Windows games by using
## the Windows Steam client in a Wine virtual desktop.

Hi @Ryochan7 . Thanks for making this launcher. After a bit of fiddling I've managed to use it to launch and play Rocket League on SteamOS.

First I see the wine virtual desktop launch, a few seconds later the game itself launches. However, it's inconsistent. Approximately one-half of my attempts end in the game being launched behind the dark blue steam animated loading screen. I can hear the game but not see it and I have to restart because the mouse and controller are grabbed by the game.

I'm wondering if you have any insight to this behavior. Would increasing or decreasing the sleep time on line 49 or 61 make it work more reliably?

I have the exact same problem as @thehack. Again, thanks for the work, ryochan@
