Gamma correction changes the colour of Windows environment when windowed
As stated in the title, the gamma correction changes the colour of the Windows environment when OpenMW is windowed.
This wouldn't be a problem, but when alt-tabbing back to Windows it seems to "reclaim" it's default colour(gamma?) and Windows returns to it's colour. This restoration done by Windows unfortunately also affects OpenMW so upon reentering it is at some arbitary gamma level that corresponds to that of Windows correction or default.
To fix this each time I alt-tab back into the game I have to nudge the gamma slider to get my desired ingame gamma level back.
I believe the way to fix this would be for OpenMW to change back to the gamma level every time the windows gets focus again.
Thanks.
