REVISION SUMMARY
  Currently, the panel leaks in when blurring the background of dialogs near it. This results in a ungly visual glitch. The panel already ignores blur of elements near it; this patch extends that behaviour to everything that has not a decoration, to make sure that the panel does not leak in. The visual bug is in fact not there anymore, see:
