I'm using SW 2016 SP2 with an Nvidia Quadro K5000 using the SW certified 354.56 drivers. Have a look at this screen cap:
The top A is an annotation. The left A is a section and the right A is a detail circle. The AA is an auxiliary view. I can't pin down exactly when this behavior started, but it is relatively new. It is zoom dependent. If I zoom in a bit, everything corrects itself, as you can see here:
I am baffled by the fact that the same text is rendered in four different ways, three of them incorrect.
Other users with the same hardware and SW version do not see this behavior.
Has anyone else come across this?
