Bug ID: 495869 Summary: There is a color mismatch on application's text being rendered when I enable HDR on my monitor (AW3423DW) as I am using an NVIDIA card Classification: Plasma Product: kwin Version: 6.2.3 Platform: Arch Linux OS: Linux Status: REPORTED Severity: minor Priority: NOR Component: wayland-generic Assignee: kwin-bugs-n...@kde.org Reporter: phamtruonggiang...@gmail.com Target Milestone: --- Created attachment 175573 --> https://bugs.kde.org/attachment.cgi?id=175573&action=edit Color mismatch when opening firefox and see the color mismatch in the bookmarks SUMMARY: When I enable HDR option on my monitor(AW3423DW) under Wayland with my NVIDIA card by adding KWIN_DRM_ALLOW_NVIDIA_COLORSPACE=1 in /etc/environment. When I tick the enable HDR option, applications couldn't render with correct colors as I would see some color mixes when I move applications to certain places on my monitor(most noticeable under konsole and firefox). Although the method can solve this issue, I can still see color mismatch but less noticeable. The latest NVIDIA driver I have for this issue is 565. This problem still persists in Plasma 6.2.2 but the black screen when leaving hdr enabled when login into Wayland is fixed after upgrading to 565. I have reported this to NVIDIA developers but they haven't responded(https://forums.developer.nvidia.com/t/565-release-feedback-discussion/310777/113) STEPS TO REPRODUCE 1. Add KWIN_DRM_ALLOW_NVIDIA_COLORSPACE=1 in /etc/environment 2. Enable HDR 3. Open applications under Plasma like Konsole and Firefox ( See the bookmarks for the effect) OBSERVED RESULT Texts in the applications like Konsole and Firefox would have mixed colors when moving ( can be seen even without moving) EXPECTED RESULT Applications under Plasma should have their color be consistent regardless of where it was moved SOFTWARE/OS VERSIONS (available in the Info Center app, or by running `kinfo` in a terminal window) Operating System: Arch Linux KDE Plasma Version: 6.2.3 KDE Frameworks Version: 6.7.0 Qt Version: 6.8.0 Graphics Platform: Wayland ADDITIONAL INFORMATION -- You are receiving this mail because: You are watching all bug changes.
