Created attachment 180921 [details] screencast from Dolphin SUMMARY When video is playing, "Prefer color accuracy" doesn't working. I know it's trivial and actually Zamundaaa solved most of the issues of lack of API from AMD, but I reported maybe give a clue to improve it. STEPS TO REPRODUCE 1. Enable night mode and Prefer color accuracy. 2. play a video in full screen (e.g using mpv, I uploaded sample video) OBSERVED RESULT Black and white line pattern disappears on sample video EXPECTED RESULT "Prefer color accuracy" also apply to full screen video Operating System: Arch Linux KDE Plasma Version: 6.3.4 KDE Frameworks Version: 6.13.0 Qt Version: 6.9.0 Kernel Version: 6.14.4-zen1-2-zen (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 5600H with Radeon Graphics Memory: 15.0 GiB of RAM Graphics Processor 1: AMD Radeon RX 6600M Graphics Processor 2: AMD Radeon Graphics ADDITIONAL INFORMATION I saw this issue both with mpv and firefox video player
