Hey vikhik,
Did some checking with some colleagues. This is a bug and I am currently testing this bug and I will get back to you as soon as I’ve opened a ticket.
Thanks,
I have opened a ticket for revision by our development staff. The ticket number is UE-18369. Thank you for reporting this bug.
Sorry, thought the title gave it away. It’s the tooltip (mouse over Enable Metal/High-end mobile rendering preview")
Glad you found it
