I can confirm this not on windows, but on Plasma Wayland, where per-screen scaling is also possible. I am currently working on fixes for some of these issues---hang on. See https://invent.kde.org/graphics/okular/-/merge_requests/368 Doesn't fix the problem reported here, but it is related. *** Bug 435073 has been marked as a duplicate of this bug. *** *** Bug 435669 has been marked as a duplicate of this bug. *** |
Created attachment 135716 [details] 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
