What do you mean by that?

I'm fairly certain I have Phil's "Improve VCHIQ cache line size
handling" patch series applied if that's the one you mean, I will
check (I'm currently dealing with 4 different kernels for maintenance
so I'm sorry if my memory isn't exact).

That was the command line, it pops up a GUI and then just taking a
still. The version is the latest upstream which is 1.16.3.

Yes, it's on my list.

Well like so much stuff on the Raspberry Pi there's users that are
testing it and want to use it so when people bother me I test it and
provide feedback to the patches, if you don't want feedback I'll stop
testing and just disable it and send people upstream for details so
they don't bother me!
