I can confirm this issue as well. When zooming in on a 4.7MiB, 2-page PDF
containing a large bitmap image (it's a scan), everything becomes pixelated and
stops loading. Okular's memory usage went up to over a gigabyte, with about 25%
CPU usage as well. It also spawned a second process which was stuck at ~25% and
didn't stop when I closed the window.

Running Okular from the terminal reveals that it somehow runs out of memory:

org.kde.okular.core: Running out of memory on page 1 (17333x25160 px);

This does not happen in other PDF readers like Xreader and Evince, which allow
me to zoom in and move around all I want.
