I’m having the same issues - random frame drops and sluggish animations on BOTH displays when external 4k 60Hz display is connected.
It doesn’t matter if I connect it via HDMI or thunderbolt. I’ve got MSI Stealth 15 laptop with 4060 + intel dGPU. Using latest version of cachy os + gnome 49 (wayland) and latest nvidia drivers. The issue persists when switching between hybrid / discrete modes. I tried fedora + gnome, cachyos + KDE but it is still broken. Only on X11 session it works properly, but my refresh rate is then capped at 60Hz on both displays. I tried switching
NVreg_EnableGpuFirmware=0
but it doesn’t change the situation.
I’m not using fractional scaling. Also when I change external display resolution from 4k to full hd it is a little bit better.
