Apologies! I got my numbers crossed. The bug is NOT fixed in the mainline kernel! I had loaded a prior kernel from 16.04 (v.4.4). That was what I reported on. Kernel v4.13.0-041300rc4-(4.13.0-041300rc4.201708062231) still has screen tearing. I will remove the tag and replace it with 'kernel-bug-exists-upstream'.
