  Thank you for your response. Let's hope that there will be a backport

Hello, I've also suffered evince slow opening file problem.

Ever since Debian 10.7 or later will this slow opening problem occurs.

However, I manage to solve this by adding the following line in ~/.xinitrc:

dbus-update-activation-environment --systemd DBUS_SESSION_BUS_ADDRESS
DISPLAY XAUTHORITY

This solution is from the following url:

https://bbs.archlinux.org/viewtopic.php?id=224787

After adding this line to my ~/.xinitrc. the problem is solved.

I've tested it to load your CBR file, and it works like a charm.

Please consider this is a bug and the above is the solution.

Thank you!

Best Regards,
