I use (L)ubuntu Zesty. If I call evince myfile.pdf, I get some warnings before the app comes up:

So, with the last error I'm guessing its hopeless since I'm not going to start fiddling with the app's code. But can I tweak the CSS files mentioned so as to avoid the warnings? If so, how? I don't quite understand these warnings.
