Summary: Okular freezes when filling out forms

Product: okular
Version First 26.04.1

OS: Linux
Status: REPORTED

The PDF I am getting the crash with
DESCRIPTION
Okular freezes when filling out form PDFs after a certain amount of time/after
switching between form boxes. When frozen it must be killed either via ctrl+c
in the parent terminal or (if opened via GUI) by `kill -9 <PID>`. Doesn't seem
to be a poppler backend issue because xreader can handle it just fine.
Tracking resource utilization with `top` there still seems to be plenty of
allocated memory available, too (virt 855848 | res 157908).
STEPS TO REPRODUCE
1. Open Form PDF in Okular (the pdf giving me issues is attached)
2. Click "Show Forms" in the dropdown box which notifies you of form content to
enable form filling
3. type for a few seconds, the freeze usually seems to happen after switching
between boxes a few times (either through tab or through clicking)
OBSERVED RESULT
okular freezes after a little bit of time (~10s-60s, variable) while fililing
forms
EXPECTED RESULT
seamless form filling, able to switch between form boxes freely without the
program suddenly freezing
