SUMMARY My monitor supports VRR, but it has a completely messy implementation in hardware. My screen keeps blinking every time the frame rate changes. So I just turned it off long time ago. Today I updated to version 6.2.5 and started blinking again so it means VRR was turned on again even it being turned off in settings and on my monitors settings (it is clearly overwriting my monitor's settings - if I set HDR on in settings, for example, it turns on my monitors HDR even though I turned it off in my monitor long time ago as well). I updated to 6.3 Beta 2 to test (as shown below by kinfo command) and the problem persists. STEPS TO REPRODUCE 1. Turn off VRR on KDE Wayland OBSERVED RESULT Blinking screen every time fps changes. EXPECTED RESULT Only turn on VRR when explicit marked as on in my kde settings. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.2.91 and 6.2.5 KDE Frameworks Version: 6.10.0 Qt Version: 6.9.0 Kernel Version: 6.13.1-zen1-1-zen (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 3600XT 6-Core Processor Memory: 23.4 GiB of RAM Graphics Processor: AMD Radeon RX 7600 XT ADDITIONAL INFORMATION Probably some flag to turn VRR off completely is not working correctly.
Please attach the output of drm_info when it's supposed to be off but isn't.
Created attachment 177956 [details] drm_info as asked by Zamundaaa <xaver.hugl@gmail.com> I tested a little bit more yesterday and when VRR is off it keeps changing my monitors refresh rate from 165hz to 106hz (I saw it on my monitors builtin fps counter). I found a workaround, if I keep my monitor at 60hz the blinking disappear.

KWin tells the driver to turn VRR off: > "VRR_ENABLED": range [0, 1] = 0 So this is a driver bug. You can report it at https://gitlab.freedesktop.org/drm/amd/-/issues
