Comment 3 Jari Tahvanainen 2016-09-08 09:26:00 UTC 
based on the CI systems I would propose this to be closed.
The case basic-cursor-vs-flip-varying-size has been having pass verdict on APL for more than two weeks.
Luis, please retest.

I confirm that for around 1 week, this is also passing on all HW on QA side. Closing it.
