I am also experiencing a steady rate of intermittent flickering once every 15-30 seconds using proprietary Nvidia drivers.
Nvidia Driver Version: 535.54.03
GPU: GeForce GTX 1650
Screen Resolution: 2560x1440 @ 144Hz refresh rate
OS: Arch Linux Kernel 6.1.37-1-lts
Desktop: Gnome 44.2 & GDM 44.1 with X11 (X Server Windowing System)
This wasn’t an issue prior to upgrading to 535.54.03. Hope they provide a fix soon.
