IT Provider here, I'm using a new HP EliteBook 645 that blows the equivalent Intel out of the water - absolutely loving my return to AMD!
But as above, I cannot sell these laptops to customers because that flashing name in a Teams meeting is going to just cause me complaints - and with evidently no fix available, it's going to cost me returns.
Graphics Driver is AMD Radeon Graphics, Version 31.0.21018.23005 - currently the latest available from HP.
This has been a problem for months and is not an isolated case: Name Labels Flashing Blinking in MS Teams video calls - Microsoft Community
AMD, if you want the corporate/enterprise markets to consider your equipment a viable alternative to the Intel monopoly you need to jump on issues like this and get them fixed.
Microsoft can get away with faults like this unfixed for months - because there's practically no alternative. But when you're trying to BE the alternative, you need to provide a smooth experience with no problems. It may seem small, but this is an absolute dealbreaker for most corporate customers.
