This is my first hour here and my first question as well.
As shown in the picture
there are huge black bars showing up in a graph, if there is an embedded excel file behind it. The bars are so huge that you can’t see the graph anymore. On the right side of the screenshot, I opened the PDF with Edge, and the huge bars aren’t there. The same goes for a browser or the acrobate PDF reader. I only found Sumatra doing this and it is deeply affecting the graph.
Are there any options to solve this issue - I would like to disable this black bars (the one lecturer has such a graph in every second slide, very annoying).
Many thanks in advance for your help,
