Comment 2 for bug 1683601

So, what is "a white version". I think you mean "vision" not "version". Though I can still figure out the meaning of the title, it would be better to rename it to "ukui-screensaver-preferences doesn't show black screen when previewing "Blank Screen" theme".

I have confirmed that this bug is obsolete because all features in screensaver-preferences have been integrated to ukui-control-center. I will mark this bug as resolved.
