Can't move back to fullscreen after Alt-Tab in force OpenGL mode

[ebigunso]

So as in the title, when I Alt-Tab out of the game which was running on full screen, it never lets me go back to fullscreen.

What happens is, I Alt-Tab out and instead of the client completely minimizing, it goes into a windowed mode of the same resolution as when it was running fullscreen, then it never allows me to go back unless I go back to the main menu and toggle the fullscreen option from the graphics settings.

When I did not force OpenGL it was all fine, with the client minimizing as it should and returning to fullscreen afterwards.

Anybody got the same issue? or any way to fix this?

Just a note: I can't run the game without forcing OpenGL now with so many mods, that it crashes the game on the second vehicle loading in the session if not. With ATM installed.

Run the game in borderless window (-popupwindow in shortcut properties); that would make your Alt-Tab experience essentially seamless.

And yes, OpenGL has this bug on some systems, mine included.

OpenGL isn't fully supported on Windows by Unity, but it's worth seeing if this issue has been reported on the Unity3D forums or issue tracker, maybe there's a workaround.

Or, try -force-d3d11 instead of openGL
