It looks like the _videoMode.overlayHeight in SurfaceSdlGraphicsManager::grabOverlay and ThemeEngine::_backBuffer::h are somehow out of sync after
starting the game in a different resolution as the gui was started with. So the overlayHeight is updated - but the backbuffer (Surface) is not resized.

This is with event recorder being active - right after starting the game and switching the resolution.

a509afdf4d COMMON: Remove resetGraphicsScale from OSystem
This function used to be called from the Engine class, but was
not longer used since commit 432fd522. The single remaining use
was an internal use in the SurfaceSdlGraphicsManager, and I kept
the behaviour there while removing the function.
