--- Comment #1 from Elite <eliteamdgam...@gmail.com> --- (In reply to Elite from comment #0) > SUMMARY > When the display is set to its default resolution and refresh rate it cause > white lines similar to old static. this also happens in the SDDM and then > things are set to default breeze. Changing DP results in the same problem. > This does not happen when on the same system from the sddm logging into > another DE. Or even if they are all fully removed. I have also tried > another monitor of the same make and model and same gpu make and model. All > give the same result. > I did notice that it happens in the sddm if I log out. > It manly happens when there any movement on screen moving a mouse moving a > blinking terminal courser. When dragging a window back an forth it doesn't > seem to happen tell the window stops moving. It used to be fixed for a while > by setting any other refresh rate not saving and going back to 144hz. I cant > capture it on video either. its almost like screen tearing or vsync is > having some issue. I have adaptive sync fully disabled on the monitor as > well. > > If the monitor is set to DP 1.2, it no longer happens but the display can no > longer hit its default refresh rate so everything looks choppy. > I don't remember this happening in 6.3.2. > > STEPS TO REPRODUCE > 1. Make sure the monitor supports DP 1.4 set refresh rate to 144hz or > higher. > 2. open a video played from a local file or a long config in kate > 3. play or scroll the text file. > > OBSERVED RESULT > White Lines randomly over the display. > > EXPECTED RESULT > no lines > > SOFTWARE/OS VERSIONS > Operating System: NixOS 25.11 > KDE Plasma Version: 6.3.5 > KDE Frameworks Version: 6.14.0 > Qt Version: 6.9.0 > Kernel Version: 6.14.7-cachyos (64-bit) > Graphics Platform: Wayland > Processors: 16 × AMD Ryzen 7 3700X 8-Core Processor > Memory: 31.2 GiB of RAM > Graphics Processor: AMD Radeon RX 7900 GRE > > ADDITIONAL INFORMATION > > System: > Kernel: 6.14.7-cachyos arch: x86_64 bits: 64 compiler: gcc v: 14.2.1 > clocksource: tsc avail: hpet,acpi_pm > parameters: > initrd=\EFI\nixos\1y87izfnn4ayic3n47x2y45s5fqajx0w-initrd-linux-6.14.7- > initrd.efi > > init=/nix/store/hnvax2y675x99bfihsmc9vmasgg868l3-nixos-system-nixos-25.11. > 20250520.2795c50/init > quiet splash rd.systemd.show_status=false rd.udev.log_level=3 > udev.log_priority=3 loglevel=3 plymouth.force-splash boot.shell_on_fail > psi=1 splash loglevel=0 > Desktop: KDE Plasma v: 6.3.5 tk: Qt v: N/A info: frameworks v: 6.14.0 > wm: kwin_wayland vt: 4 dm: SDDM Distro: NixOS 25.11 (Xantusia) > Machine: > Type: Desktop Mobo: ASUSTeK model: PRIME X570-PRO v: Rev X.0x > serial: <superuser required> part-nu: SKU uuid: <superuser required> > UEFI: American Megatrends v: 5031 date: 01/13/2025 > CPU: > Info: model: AMD Ryzen 7 3700X bits: 64 type: MT MCP arch: Zen 2 gen: 2 > level: v3 note: check built: 2020-22 process: TSMC n7 (7nm) > family: 0x17 (23) model-id: 0x71 (113) stepping: 0 microcode: 0x8701035 > Topology: cpus: 1x dies: 1 clusters: 1 cores: 8 threads: 16 tpc: 2 > smt: enabled cache: L1: 512 KiB desc: d-8x32 KiB; i-8x32 KiB L2: 4 MiB > desc: 8x512 KiB L3: 32 MiB desc: 2x16 MiB > Speed (MHz): avg: 4261 min/max: 560/4427 boost: enabled scaling: > driver: amd-pstate-epp governor: performance cores: 1: 4261 2: 4261 3: > 4261 > 4: 4261 5: 4261 6: 4261 7: 4261 8: 4261 9: 4261 10: 4261 11: 4261 12: > 4261 > 13: 4261 14: 4261 15: 4261 16: 4261 bogomips: 115197 > Flags: avx avx2 ht lm nx pae sse sse2 sse3 sse4_1 sse4_2 sse4a ssse3 svm > Vulnerabilities: <filter> > Graphics: > Device-1: Advanced Micro Devices [AMD/ATI] Navi 31 [Radeon RX 7900 XT/7900 > XTX/7900 GRE/7900M] vendor: Sapphire driver: amdgpu v: kernel arch: > RDNA-3 > code: Navi-3x process: TSMC n5 (5nm) built: 2022+ pcie: gen: 4 > speed: 16 GT/s lanes: 16 ports: active: DP-1 empty: DP-2, HDMI-A-1, > HDMI-A-2, Writeback-1 bus-ID: 0d:00.0 chip-ID: 1002:744c class-ID: 0300 > Display: wayland server: X.org v: 1.21.1.16 with: Xwayland v: 24.1.6 > compositor: kwin_wayland driver: gpu: amdgpu display-ID: 0 > Monitor-1: DP-1 model: LG (GoldStar) ULTRAGEAR serial: <filter> > built: 2020 res: 3440x1440 dpi: 109 gamma: 1.2 size: 800x335mm > (31.5x13.19") > diag: 867mm (34.1") modes: max: 3440x1440 min: 640x480 > API: Vulkan Message: No Vulkan data available. > API: EGL Message: EGL data requires eglinfo.
