Package: okular
Version: 4:20.12.3-2
Severity: important
Open a nonempty Postscript file (probably, any would do) with okular. For example, take the file mwe.ps in the attachment produced by latex mwe && dvips mwe from mwe.tex containing \documentclass{article}\begin{document}Test\end{document}. Scroll completely to the left. Observe a vertical bar on the left of the page. If the bar doesn't appear immediately, zoom out (and in) a few times with Ctrl++ and Ctrl+-. At some (seemingly random) magnifications, the bar sometimes appears (and sometimes disappears) fully or partially. Sometimes, colored dots are scattered on the otherwise black bar. Two screenshots of okular mwe.pdf with a bar are attached: one at 33%, another at full page for the same small window size.
The severity is raised because the bar distracts the reader and gets increasingly annoying in the long run. I run Debian bullseye with a few updated packages from bookworm.
The black vertical bar shouldn't be there.  I kindly ask for a fix.
Gratefully,
