Hi, I solved by a workaround, I disabled GPU = acceleration material.
To do that make a right click on Teams icon in task bar and Settings = Disable material acceleration.
To be honest, It's not used.... I don't see the difference except that my PC doesn't make fan noise ;-)
It's a workaround, but clearly Microsoft team in charge of Teams Dev and particulary 3D using need to check !
This is the one thing that seemed to help a little. Not enough though, it's just a pig of a program.
I have since banned the use of Teams throughout our company as it simply causes time to be wasted on any system it runs on. Sad, as it was a good idea before being rammed down our throats without being tested for purpose.
This has caused some issues in client comms, but I am recommending to all clients that they follow suit and working around the issue as needed.
What a joke of product.
