System Process: High CPU utiliziation after sleep when Radeon GPU is active

HP Recommended
Elitebook 850 G5
Microsoft Windows 10 (64-bit)

I have an Elitebook 850 G5 with a Radeon 500 Series GPU. I updated all the drivers using HP Support Assistant (side note: the update of the Conexant HD Audio Driver failed).


The problem which I have: after wake up from sleep the "System" process utilizes one CPU core when the Radeon GPU is enabled. After I disable it in the device manager the CPU usage drops to normal.


See the Performance Monitor screenshot below:
