I usually save slide presentations in pdf format. When using Evince to open those pdf files, the fonts always look ugly, with "serrated" borders. I've tried opening same files with Okular and Adobe Reader, and they look OK. However, I'm using MATE desktop environment, and Okular sends error message (something like "could not open /home/...%i) and opens at least two instances every time I execute it; on the other hand, Idon't like Adobe because it is not free.
Any clue on how to improve font rendering in Evince?
