Flickering in Full-Screen Apps (VS Code, Chrome, Cursor) on External Monitor

[Aravisian]

This user reported (by extension) an interesting issue with the Nvidia 570 driver (You and I are both using it).

Have you tried switching to a different Nvidia driver?

Or tying the boot parameter nvidia-modeset.hdmi_deepcolor=0

Zorin Os won't start, "Out of Scale"

i installed the Nvidia driver 570, and before restarting, add the parameter "nvidia-modeset.hdmi_deepcolor=0" at the end of the parameter line of the file /etc/default/grub. After that, run the command "sudo grub2-mkconfig" to apply the parameter on the next boot, and restart. [Captura de tela de 2025-04-25 20-36-28]
