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.
