Comment:

 Oh, ok, it's this:

  1. Set background to dim
  2. Restart app
  3. Background is dimmed, but checkbox is unset.

 It doesn't always happen - I can't reproduce 100%. But the really weird
 thing is, when stepping through, the relevant variables are completely
 consistent with the background *not* being dimmed.
 initParams.dim_background is false, TileSet.init gets called with
 dim=false, alpha gets set to 1, and when alpha gets queried to set the
 checkbox state, it's 1, so the checkbox *should* be unset.

 So two questions: why is initParams.dim_background false, and why on earth
 does the background display dimmed when tileset.alpha=1? But as I can't
 reliably reproduce, it's hard to investigate.
