Bug#1036115: Evince draws the pages of Postscript files with black vertical bars on the left

[Al Ma]

Package: evince
Version: 3.38.2-1
Severity: important
Open a nonempty Postscript file (probably, any would do) with evince. 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}. Observe two black vertical bars on the left of the page: one in the main view and another in the thumbnails. If the bars don't appear immediately, play with evince a bit: change the zoom or reload with Ctrl+R a few times. Upon some reloads, the bars appear, and upon other reloads, the bars disappear (not necessarily simultaneously). A screenshot of evince mwe.pdf with two bars is attached.
The severity is raised because the bars distract the reader, and in the long run (and the bug has been there quite long, probably over a year), they get increasingly annoying. (If my memory doesn't fail me, the bars might have even appeared once in a printout, though it's a long time ago, and I wouldn't vouch for it today because it was seldom and might have been specific to a file, ergo, not necessarily related to the bug here.) I run Debian bullseye with a few updated packages from bookworm.
The black vertical bars shouldn't be there.  I kindly ask for a fix.
Gratefully,
AlMa
