            Bug ID: 332900
           Summary: rasterisation issue when using TikZ's doube line
    Classification: Unclassified
           Product: okular
           Version: 0.18.3
          Platform: Kubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: PDF backend
          Assignee: okular-devel at kde.org
          Reporter: yasinzaehringer+kde at yhjz.de

Okular does not correctly rasterise the attached PDF depending on the zoom
level. The problem is that two rectangles with slightly different width are
drawn on top of each other to produce an equal sign. It seems to be an
Okular-only issue. (I have not checked that many readers, in particular I
haven't checked Adobe Acrobat.)
The LaTeX code to produce the PDF can be found here [1].

Reproducible: Always

Steps to Reproduce:
Load the PDF and try different zoom levels. (The 'bad' zoom levels seem to
dependent on the screen resolution.) On my netbook (1024x600), the issue
appears below 200%.
Actual Results:  
See the attached jpeg.
