I’m experiencing screen tearing on a new laptop running NixOS. When attempting to fix it with a configuration change such as those mentioned in the NixOS manual (e.g. changing
services.xserver.deviceSection), or changes to
services.picom, should a reboot be necessary to test the fix?
I’ve been testing with just
nixos-rebuild test. So far nothing has helped, and I wondered if some configuration changes might actually require a reboot to take effect.
For context, this is on a ThinkPad X1 Carbon gen 9, running xmonad and no desktop environment. The screen tearing occurs around 15% to 20% from the top of the screen when scrolling vertically (e.g. in chromium) or watching video.
