Dear Anand Sri, we have the same issue. We used to generate our participant document out of Powerpoint (Current Version 16.14.1) for Mac (Current Version 10.13.5) with the print menu and Safe as Adobe PDF -> High Quality Print -> (Acrobat Pro DC, 2018.011.20040) The file from about 2 weeks looked fine but yesterday we got an unusable pdf. Images are compressed and lines are much thicker. Was there an update deployed within the last two weeks which could cause this issue? Thanks and best regards, Hari
