    Hi there,

    First time using Deepin - Great distro

    So, how i fixed the screen tearing:

    Check if your V-sync is active:
    1. sudo cat /sys/module/nvidia_drm/parameters/modeset
    Copy the Code
    If the output is Y then it is active, if N do the following:
    create a new file
    1. sudo nano /etc/modprobe.d/nvidia-drm-nomodeset.conf
    Copy the Code
    and insert the line:
    1. options nvidia-drm modeset=1
    Copy the Code

    Then:
    1. sudo update-initramfs -u
    Copy the Code
    Reboot

    Then check again with:
    1. sudo cat /sys/module/nvidia_drm/parameters/modeset
    Copy the Code

    If it is still N, copy the file in /etc/X11/
    then again:
    1. sudo update-initramfs -u
    Copy the Code
    Reboot.

    Have a nice day to all!
