Bug ID: 477438 Summary: Apps using wp_fractional_scale_manager_v1 look blurry Classification: Plasma Product: kwin Version: 5.27.9 Platform: Arch Linux OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: wayland-generic Assignee: kwin-bugs-n...@kde.org Reporter: ava...@disroot.org Target Milestone: --- SUMMARY I've been trying the experimental wp_fractional_scale_manager_v1 support to see if things looked sharper, and was surprised to see it perform much worse than downscaling. Apps using this protocol look blurry, and in the case of Firefox, some UI elements even break. STEPS TO REPRODUCE 1. Apply 150% of scaling (I'm using a 32" 4K monitor). 2. Run GNOME Clocks 45.0 with GTK 4.12.4 and the env `GDK_DEBUG=gl-fractional`. 3. Notice the blurriness of the entire app. Using the same scaling: 1. Run Firefox 119.0.1. 2. Set the about:config flag `widget.wayland.fractional-scale.enabled` to true. 3. Restart Firefox. 4. Observe the blurriness and broken menus. OBSERVED RESULT Things blurry and broken. :( EXPECTED RESULT Thinks ultra crisp and sharp. :) SOFTWARE/OS VERSIONS Linux/KDE Plasma: Parabola (available in About System) KDE Plasma Version: 5.27.8 KDE Frameworks Version: 5.112.0 Qt Version: 5.15.11 ADDITIONAL INFORMATION -- You are receiving this mail because: You are watching all bug changes.
