I'm trying to view a pdf in Adobe Acrobat X Standard and some of the lines are missing. When I open the same pdf in both edge and chrome, it works and everything is there. Also have tried on a second computer that has Acrobat 8 Standard installed, and it has the same problems. No numbers or letters are missing, just lines. Both computers are completely up to date.
Are the lines still missing when you change the zoom factor? Sometimes very thin lines fall "between" two columns or rows of pixels, and when you e.g. zoom in, the line will become visible.
Thank you very much! That did indeed fix it - had to zoom for 90% to 100%
