Bug ID: 459937 Summary: Okular looks blurry on macOS with Retina display Classification: Applications Product: okular Version: 21.08.3 Platform: macOS (DMG) OS: macOS Status: REPORTED Severity: major Priority: NOR Component: general Assignee: okular-devel@kde.org Reporter: stefan.cooper1...@gmail.com Target Milestone: --- Created attachment 152561 --> https://bugs.kde.org/attachment.cgi?id=152561&action=edit Top: Observed result, Bottom: Expected result STEPS TO REPRODUCE 1. Download Okular from here: https://binary-factory.kde.org/job/Okular_Release_macos/lastStableBuild/ (I downloaded build #792) 2. Start okular after installing it OBSERVED RESULT The resolution of the Okular app interface looks blurry (e.g. the fonts or icons) on my Retina screen and the PDF also seems blurry. It also seems that the dark mode is not supported. EXPECTED RESULT Sharp resolution of the Okular app and at least the default light mode of the app if it does not support dark mode. SOFTWARE/OS VERSIONS macOS: 12.6 (Monterey) (inside "About okular") Okular Version: 21.08.3 KDE Frameworks Version: 5.87.0 Qt Version: 5.15.2 (built against 5.15.2) PROPOSED SOLUTION Edit the Info.plist inside okular.app/Contents/Info.plist and add following 3 keys & values: <key>NSRequiresAquaSystemAppearance</key> <true/> <key>NSPrincipalClass</key> <string>NSApplication</string> <key>NSHighResolutionCapable</key> <true/> This seems to work for me, but it may not work for everyone. These are the reasons why I added those 3 keys & values: * I found this in the docs from qt which might help in terms of the Hi-DPI problem on Retina screens: https://doc.qt.io/qt-5/highdpi.html#macos-and-ios * I found this in the docs from Apple (notice the section "Opt Out of Dark Mode"): https://developer.apple.com/documentation/appkit/nsappearancecustomization/choosing_a_specific_appearance_for_your_macos_app In the attachments you can see the before & after result of my changes to the Info.plist. -- You are receiving this mail because: You are the assignee for the bug.
