<pre>GPU: R9 390
GPU manufacturer: Gigabyte
Kernel: 4.5, 4.6, etc
Firmware: both hawaii_smc.bin and hawaii_k_smc.bin
Hello,
I am experiencing heavy LCD screen flickering in OpenGL apps when automatic GPU
power management is enabled.
The flickering is related to mclk transitions. Forcing mclk=1.5GHz, and letting
sclk be controlled by DPM, removes the flickering.
