AMD 8350. 8Gb mem
Gigabyte GA-970A-UD3P mobo. (FC bios)
RX-570 graphics card (19.12.3)
Win 10 x64 (1909)
I use Media Portal on my HTPC and the new 2020 Radeon Settings (Driver package ver. 19.12.2 &3) fails to start after a resume from hibernation but only if Media Portal 1 was also running when the HTPC was put in standby. Radeon Settings does not react at all if the icon on the taskbar is double clicked and when I attempt to run the app from win10 start menu then a transparent window appears on the display which does not react to anything except killing the task from the task manager. Rebooting the HTPC returns the app. to normal operation. If MP is closed prior to putting the HTPC is standby there is no problem, also 2019 driver versions (19.8.2 tested) don't suffer from this problem. As far as I can tell the GPU continues to function OK when the settings app is in this failure mode.
Win 10 Fast Startup is disabled.
It seems there is a conflict between Media Portal and the Radeon Settings app. that has been introduced with the latest 2020 package.
Any ideas on how to proceed on this would be most welcome.
