Screen does not refresh running Webex

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

Re: Screen does not refresh running Webex

Hello,

Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.

You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).

Then perform these steps:

  • Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
  • In the Firefox options window click the Advanced tab, then select "General".
  • In the settings list, you should find the Use hardware acceleration when available checkbox. Uncheck this checkbox.
  • Now, restart Firefox and see if the problems persist.

Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:

Re: Screen does not refresh running Webex

Thank you,

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.

Thank you,
