Expected.

To high.
With 1 or more identical monitors?
Compare Alex's latest >=2 identical monitor patches.
I get the same even on Polaris (Alex?).

That is currently the expected 'auto' clk transition bug.
If someone set the clks to low/high flickering can't happen.

That's the 'new' interesting part that Andrew, Robert and you find with Navi.
The suspend / resume (with later high/low) 'cycle' which led to much lower
power consumption.

Which I couldn't verify on my Polaris system (with 2 identical HDMI monitors)
currently.
With 'low' and 2 identical HDMI displays I get the below under
'amd-staging-drm-next':

GFX Clocks and Power:
        300 MHz (MCLK)
        300 MHz (SCLK)
        600 MHz (PSTATE_SCLK)
        1000 MHz (PSTATE_MCLK)
        750 mV (VDDGFX)
        32.174 W (average GPU)

PSTATE_SCLK and PSTATE_MCLK do NOT drop and much to high W.
NO flickering due to 'low'.

I'll point Alex to this thread.
