Hello everyone. Sorry for this topic, I'm new in Linux and just begin learning Linux. I've installed Manjaro Gnome recently, and I ran into a problem: my screens are flickering. It's not critical, because I can still work with this issue, but it really annoys for me. Blink effect looks like you record screen from the camera, like that: https://youtu.be/oH9wkQkgMcI?t=178s
I have GeForce RTX 2070 SUPER, the first monitor connected via HDMI, the second monitor connected via HDMI-DP cable, but both monitors are flickering.
I tried changing GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub, I added i915.enable_psr=0. After that I ran sudo grub-mkconfig -o /boot/grub/grub.cfg, but it ddin't help me.
