nvidia-drivers 升級至 580.126.09,閃爍問題

 在 Arch Linux,已發生此問題,一直以為是顯卡的問題。

直到 Gentoo,也升級到新版後,發生閃爍的問題。降回舊版驅動,就沒有此問題,因此確定是新版驅動的問題。

---------------------

NVIDIA driver version 580.126.09 is causing significant screen flickering issues, particularly on Linux (Xfce/Wayland) with applications and desktop components. Users report this issue as a regression from previous stable drivers. Immediate fixes include rolling back to a known stable driver, disabling the compositor, or waiting for a patch. 
Key Troubleshooting Steps for 580.126.09 Flicker:
  • Roll Back Driver (Linux/Windows): If the flicker started immediately after updating to 580.126.09, revert to the previous version via your package manager (Linux) or Device Manager (Windows).
  • Disable Compositor (Linux): On Xfce, turning off the compositor in settings may stop the flashing.
  • Clean Reinstall: Use DDU (Display Driver Uninstaller) to completely remove the current driver before reinstalling to rule out corruption.
  • Wait for Hotfix: NVIDIA frequently releases hotfix drivers for reported regressions.
  • Check Hardware/Cables: Ensure display cables are secure, as driver changes can sometimes exacerbate minor physical connection issues. 
For Linux users, this issue appears to be heavily affecting desktop environments, and reverting to the 580.95.05 driver has been reported as a workaround.

Other drivers may also be built using VSCode, but this is not supported by the project for the time beeing.
