I have a MacBook Air which works perfectly fine for screen-sharing within Google Hangouts BUT not within a Canvas Conference. Since I'm teaching an online community college class, I really need to be able to share my screen with students!
The problem is with the display itself. When the screen-sharing window appears, the display is messed up--I see the colors that are on my screen, but everything is a diagonal swirl of lines--nothing other than the colors indicate that it's even my screen.
I've run this by both my college's contact and the after-hours support to no avail. Nobody has any ideas on how to diagnose the problem.
I've tried three different browsers--Safari, Firefox, and Chrome. All exhibit the exact same behavior.
