Comment 1 Dhananjay Arunesh 2019-07-17 07:40:49 UTC

Created evince tracking bugs for this issue:

Affects: fedora-all [bug 1730584]

Comment 2 Marek Kašík 2019-07-18 14:09:56 UTC

This was fixed in 3.28 according to the upstream bug. Are you able to reproduce this on a supported version of Fedora? I see some artefacts due to wrong sizes but no invalid write.

I am not able to reproduce this on evince-3.32.0-3.fc30.x86_64, the pdf does not render at all, but no invalid writes etc.
