I'm afraid that was the wrong call, please file your own report.

In general, it's easy to mark duplicate bug reports, but it's hard to untangle
information about different problems in a single report, so it's better to
start with a separate report unless one is at least 99% sure it's exactly the
same problem. Also, lots of different causes can produce similar symptoms.

BTW, that's not what "tearing" refers to in the display context.
