*** Apologies for some windows terminology, I am a transplant. When mousing the cursor over the "Taskbar" Panel (icons, and "system tray" icons), portions of the taskbar and mouseover notifications/info flicker when the user has multiple monitors with different refresh rates connected (2 in this case). The issue presents when two different refresh rates are selected, but does not present when the same refresh rate is selected between both monitors. *** SUMMARY STEPS TO REPRODUCE 1. connect two monitors with different refresh rates selected (160hz & 144hz are what I noticed the issue on) 2. Mouse over the "Taskbar" panel 3. OBSERVED RESULT Taskbar flickers repeatedly EXPECTED RESULT Taskbar should not flicker SOFTWARE/OS VERSIONS Operating System: Fedora Linux 42 Linux/KDE Plasma: KDE Plasma Version: 6.4.4 KDE Plasma Version: 6.4.4 KDE Frameworks Version: 6.17.0 Qt Version: 6.9.1 Wayland ADDITIONAL INFORMATION Kernel Version: 6.16.3-200.fc42.x86_64 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 9800X3D 8-Core Processor Memory: 64 GiB of RAM (60.5 GiB usable) Graphics Processor 1: NVIDIA GeForce RTX 4070 - NVRM version: NVIDIA UNIX Open Kernel Module for x86_64 575.64.05 Release Build (dvs-builder@U22-A23-13-1) Fri Jul 18 16:00:10 UTC 2025 GCC version: gcc version 15.2.1 20250808 (Red Hat 15.2.1-1) (GCC)
Thanks for the bug report. Unfortunately, this is an NVIDIA GPU issue, like virtually all the other weird random graphical glitches end up being. Please report this issue to the NVIDIA folks, either by sending an email to linux-bugs@nvidia.com or making a post at https://forums.developer.nvidia.com/c/gpu-graphics/linux. It would be helpful to the NVIDIA developers if you could run nvidia-bug-report.sh and attach the resulting file in your report. Thanks!
Created attachment 184730 [details] attachment-3535631-0.html Thank you for your reply, I will do just that! This was my first bug report, and I've recently signed up to volunteer for KDE support, so I'm looking for areas where I can be helpful. I come from a windows sysadmin background, but I daily drive fedora KDE on my personal device. Do you have any advice of where I could be the most useful, perhaps in user support?
