I have tried changing the engine with both the newer and the old versions of the app cannot make 1.11 stick. The older version works fine with 1.21.1. Let me do a backup and update to try to get a screenshot.
I originally went
Version 8.8.15-fdroid (4865) to Version 8.8.30-fdroid (4895) to Version 8.8.40-fdroid (5098)
Now I went
Version 8.8.15-fdroid (4865) to Version 8.8.40-fdroid (5098)
and the issue persists in the newer versions.
Also the description in f-droid for librera states:
“For better security, the F-Droid version, is based on the latest MuPDF 1.16.1 and does not require access to the Internet.”
But 1.16.1 is not even an option now.
You are totally right, don’t know why I didn’t go to their GitHub first.
Now I did and release 8.8.68 fixes the issue. Hopefully will be in f-droid repository soon.
Thank you.
