When I try connecting my monitor to the motherboard which > outputs signal from my AMD iGPU, everything looks fine. > > STEPS TO REPRODUCE > 1. Run KDE Plasma like normal with Nvidia GPU. > 2. Open multiple windows of any programs and try moving / resizing them. > > OBSERVED RESULT > The window movement and cursor stutters, looks as if it was moving at half > the monitor's refresh rate. > > EXPECTED RESULT > The windows and cursor move smoothly at the monitor's refresh rate. > > SOFTWARE/OS VERSIONS > Operating System: Fedora Linux 44 > KDE Plasma Version: 6.8.1 > KDE Frameworks Version: 6.31.0 > Qt Version: 6.11.2 > Kernel Version: 7.2.11-200.fc44.x86_64 (64-bit) > Graphics Platform: Wayland > Processors: 12 × AMD Ryzen 5 7600X 6-Core Processor > Memory: 32 GiB of RAM (30.4 GiB usable) > Graphics Processor 1: NVIDIA GeForce RTX 5070 Ti > Graphics Processor 2: AMD Ryzen 5 7600X 6-Core Processor > Manufacturer: ASRock > Product Name: B650M-HDV/M.2 > > ADDITIONAL INFORMATION > I am using Nvidia drivers from RPM Fusion, driver version is 615.78.08. > KWIN_DRM_DISABLE_TRIPLE_BUFFERING=1 works as a workaround.
