I am experiencing the same on my Intel NUC (7PJYH). Screen tearing, almost like a “seizure”.
System runs fine on 5.8.18-1, but upgrading to 5.9.10-1 ensures screen tearing. Also upgrading to the experimental kernel 5.10.xx causes these screen tearing issues to appear.

Will update with an [EDIT] as I don’t have the 20-intel.conf on my system.
[EDIT]: Adding the 20-intel.conf file with enabled TearFree didn’t resolve the issue on 5.9.10-1 unfortunately. Going back to 5.8.18-1 for now.
