AMD FirePro W4100 Graphics card, worked fine under 1809, after upgrade to 1903 I get a Code 31 device not working properly.
I was running win10-64bit-radeon-pro-software-enterprise-19.q1.2-mar29 before the upgrade
after upgrade, I tried updating to the latest win10-64bit-radeon-pro-software-enterprise-19.q2-may6
Tried reverting to an older driver radeon-pro-software-adrenalin-edition-17.12.1-dec11
Tried uninstalling everything and letting windows update install its version 126.96.36.199
