I am using firefox 22 and using Webex One-Click on the desktop
Everything runs fine and I am able to view sharing fine, however when I share my screen I run into a number of screen update issues.
Dropdown menus on any website do not work.
When clicking on a drop down menu, often you will see a border or outline of where box would be but no selections are available. After waiting for ~10 seconds the selections become visible.
When I stop sharing screen is frozen white and I need to end firefox and restart.
I am not using the webex plugin for firefox, and firefox is the only browser this happens in. IE, Chrome both work fine. This occurs on
2 Personal Laptops both running windows 7 64
1 Work Laptop running Windows 7 32
This solved the issue and let me track down the root cause.
Firefox Hardware Acceleration does not work in the "Windows 7 Basic" Theme so this is not related to WebEx at all. WebEx, when sharing your screen switches your theme to Basic or something similar to it.
When I manually set my theme to basic, have Hardware Acceleration on, and start Firefox I get the same type of graphical glitches. The top menu bars for example do not fill in for 10 seconds or so.
However turning this off solves it completely on 2 of my computers at least, I will see about the other two later.
