--- Comment #1 from Oliver Sander <oliver.sander at tu-dresden.de> ---
Some of the calls to `setDevicePixelRatio` where probably introduced by me. The
deep-copying was not intentional.  I am not very proficient in Qt programming,
and I wasn't even aware that these calls trigger a deep copy.

Does https://invent.kde.org/graphics/okular/-/merge_requests/612 fix your issue
by any chance?
