In my log output I get the following 5 warnings:

I tried to solve this warnings, but I cannot find where these overfull \hboxes are. On lines 80-84 there is no text in my texfile. Now I removed some text from my source file (around 150 pages) in order to identify where the 5 warnings come from. I managed to make them disappear by deleting some random parts of my text, but this did not answer my question. Also deleting some completely other random text, could remove the warnings. And this included lines which clearly did not produce a bad box. Because of this strange behaviour I cannot provide a minimal working example. Maybe you can tell me from my log file where the warnings come from. I am sure that there are no particular lines in my tex which produce these warnings, but it is more a global error coming from my settings.
\overfullrule=5ptand look for the black swatches? – Rmano Jul 01 '19 at 09:26
