Bug ID: 406696 Summary: Kwin should have sane defaults for surface format Product: kwin Version: 5.15.4 Platform: Neon Packages OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: wayland-generic Assignee: kwin-bugs-n...@kde.org Reporter: mikolabr...@ukr.net Target Milestone: --- Created attachment 119521 --> https://bugs.kde.org/attachment.cgi?id=119521&action=edit Watch the sky At the moment default color format for new wayland clients is something like 565 - 16 bit clolor. If the client does not change it, then this format will be used for all rendering. Qt apps usually do not change it. This results for severe color banding, especially in videos. Good example is this video when wached in Falkon: https://www.youtube.com/watch?v=Bey4XXJAqS8 At the same time Firefox running in Xwayland has no color banding. STEPS TO REPRODUCE 1. Open https://www.youtube.com/watch?v=Bey4XXJAqS8 in Falkon runing as native Wayland client 2. Open same video in Firefox runing as X11 client 3. Compare color banding on frames with big gradients OBSERVED RESULT Falkon has severe color banding EXPECTED RESULT Videos look the same in bouth browsers SOFTWARE/OS VERSIONS Linux/KDE Plasma: Neon Dev stable (available in About System) KDE Plasma Version: 5.15.4 KDE Frameworks Version: 5.58.0 Qt Version: 5.12.0 -- You are receiving this mail because: You are watching all bug changes.
