The flickering issues I have with 75hz are gone after forcing profile to high.

The disables mclk switching by forcing the clocks to high. What modes and refresh rates exhibit the problem?

Any resolution at 75hz. My FullHD modelines are:

[ 802.898] (II) AMDGPU(0): Modeline "1920x1080"x0.0 148.50 1920 2008 2052 2200 1080 1084 1089 1125 +hsync +vsync (67.5 kHz eP) [ 802.898] (II) AMDGPU(0): Modeline "1920x1080"x0.0 170.00 1920 1928 1960 2026 1080 1105 1113 1119 +hsync +vsync (83.9 kHz e)

First one is 1080p@60hz (good), second is 1080p@75hz (flickers)
