HBCC Memory Segment causing GPU clock instability

Hello all,

 

I have noticed an issue with HBCC Memory segment being turned on on RX Vega 64.  After exiting a game, or even alt tabbing gpu clocks remain slightly elevated, Core clock ranging from 400-800mhz and memory clock 167-800mhz.  This has been causing system instability and crashes.  I am on a new install of Windows 10.  No issues are observed with HBCC Memory Segment disabled, GPU clocks down clock correctly in idle state.  This is present on the last three driver releases, 19.1.1, 18.12.3, and 18.12.1.1.  Anyone else have this issue?
