While attempting to run the tutorials, I noticed 2 issues, and confirmed the issue on both runtimes.
Selecting the cube object to insert into the scene worked fine. The next step asks me to click on the
highlighted button to apply the primitive. I searched the screen, finding only the apply in the tool options.
This was not highlighted, as well the tutorial text did not update. I proceed to the next step manually,
adding the ellipse, and finding 3d Coat coming to a screeching halt when I click the apply button.
I proceed on with the tutorial after several seconds and 3d coat was finally able to add the object.
Note, CPU usage stayed around 30% and memory usage was at 2 out of 16gb.
Completing the tutorial welcomed a message saying that the tutorial was incomplete, probably due to the
bug with apply not highlighting.
It is completely possible that some setting for my display adaptor is the culprit, I've seen AA cause selection
bugs in other 3d software.
