Comment 8 for bug 1809685

@seb128: Yes, it's really annoying. I have to be really careful not to zoom too much in and out my documents as everytime it could be the last time before evince and all it's child windows freezes indefinitely.

It seems to me like it happens in the rendering code. Reproducing sometimes need patience as there does not seem to be a deterministic way to trigger it but if you sit down scroll and zoom in and out a document for some time it will definitely happen.
