Widgets are displayed wrongly.

[Infraviored]

Maybe this is the wrong place to ask.
But I can not fix the issue that every widget I want to start has background problems.

e.g. https://github.com/closebox73/Taurus, the alcyone widget - up to date and very simple

Every time is start, the text of the widget is visible but the background is very bad.
I am using Conky manager v2.73, but also running the shell manually has the same issue.

conky: desktop window (a00010) is subwindow of root window (26e)
conky: window type - desktop
conky: drawing to created window (0x3600001)
conky: drawing to double buffer
/home/flo/.config/conky/Alcyone/scripts/wthr2: line 17: =: No such file or directory

What could be the issue here?
