            Bug ID: 433003
           Summary: PDF rendering on dual screen setup with different
                    per-screen scaling appears broken
           Product: okular
           Version: 20.12.2
          Platform: Microsoft Windows
                OS: Microsoft Windows
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: PDF backend
          Assignee: okular-devel at kde.org

Main screen (100% scale factor)

SUMMARY
I noticed that Okular renders PDF files poorly when the scaling factor differs
between the two screens of a multi-monitor setup.

STEPS TO REPRODUCE
1. Be on Windows 10
2. Have a dual-screen setup with one screen set to 125% and the other to 100%
scaling
3. Open a PDF file

OBSERVED RESULT
Rendering is broken (rendering artifacts, jagged lines, missing details etc...)
on the screen set to 100% scaling, but pixel perfect on the other

EXPECTED RESULT
Rendering is pixel perfect regardless of screen scaling differences

SOFTWARE/OS VERSIONS
Windows: Windows 10 build 19042
KDE frameworks: 5.79.0
Qt Version: 5.15.2
