SCI: LSL6: Objects disappear temporarily after using the controls dialog

[eriktorbjorn]

I've tested this with the latest development version of ScummVM.
English low-resolution version. Either talkie or non-talkie.

1. Start the game and skip the intro.
2. Open the Controls dialog.
3. Press the "?" button and look at a few help texts. (I don't know how much of this is absolutely necessary.)
4. Click the "Ok" button to close the Controls dialog.

The objects that were under the Controls dialog are now no longer drawn. At lesat not until something forces them to be. In the first room, this is likely to be Larry and the receptionist. In the room to the right it may be the door, etc.

I can't reproduce this with the hi-res version.

This appears to happen when playing the original in DOSBox as well.
