If you're refering to the Retina Z2, that's right, the chip is specified
only for 90MHz pixelclock, so you've got to expect odd behaviour with
(much) higher frequencies.

The Retina Z3 can handle higher frequencies, of course, it's specified
for 110MHz, and I've tried up to 140Mhz without difficulties.
