Dear everyone,
First of all, I apologize for my lame English. I have experienced the same issue and it literally drove me crazy for hours. I tried everything I found on this post and nothing seemed to work. However, I've been able to identify where the problem was coming
from : PowerPoint vs. Zoom in my case. Every time I am annotating on my PPT slides with the Drw tool (and not the annotation tool of Zoom), it crashed yet... only with plain colors. I know, I might sound crazy atm, but I swear, when I am using gold or silver,
it works without a hitch... So, eveb if I sound silly, I thought I had to post it here.
Hopefully, it might help some of my fellows desperate teachers here ;)
