Seems to be another 6.5.5. bug. Running on Windoze 10. For no reason which I can figure out sometimes a song will appear in the preview (middle pane) with the first slide either completely or 50 per cent black. But it projects OK and if I go to edit the song it appears correctly.

Any idea what causes this glitch ( and more importantly how to get it to go away?)

Here's a screenshot link showing the issue:

and here's another example of the problem - in this case a partially greyed out second slide

I have the same problem...seems to be randon blank, or partly greyed out preview slides.
Our fix at the moment is to go into the options and change the font, then change it back again, and it resolves the corruption.
I would agree, though, that it is a bug that needs fixed.

Hi!

I am sorry about this issue. It is a bug and has been submitted to the developers and they are working on it.

Here's an example of what happens to me (that you can add the bug description)

I added a .png media content (Bunco Night graphic) to a slide and the transparent parts of the background show stuff from other slides, but when displayed, doesn't show it. It's just in the preview section.
