Alt-Tab freezes app

[mike]

Problem

Sometimes (esp when running two clients), alt+tabbing away and then going back will cause the display on one of the clients to freeze and not come back. Exiting the program is required.

This happens in Windows as well.

This seems to only be a problem when running more than one client at a time. Something that really shouldn't be attempted by anyone other than developers. As such, I'm downgrading the priority.

Investigation

Line 725 of OgreRoot?.cpp shows that the default ogre runloop does this:

while( !mQueuedEnd )
        {
            //Allow platform to pump/create/etc messages/events once per frame
            mPlatformManager->messagePump(mAutoWindow);

            if (!renderOneFrame())
                break;
        }

MV3D only calls the renderOneFrame(). That is certainly the problem, but we will need to figure out what the mPlatformManager and mAutoWindow are. :)

Solution

Did as above. mAutoWindow==self.renderWindow, and the mPlatformManager was gettable by a singleton. Seems to work now except maybe no mouse pointer when switching?
