WebEx screenshare messes up display of firefox browser

When I share my screen using Cisco WebEx, the display is almost completely destroyed when I use FireFox Quantum (59.0.1 (64-bit)). Text is hidden, there's white spaces/blocks across the webpages, etc.

I've been informed that disabling hardware acceleration resolves the display issue, but that doesn't seem like a very good solution to the problem. I use hardware acceleration with both Chrome and Edge and do not have the same display issues. I would like to continue using this browser, but this issue is rather serious due to my job relying heavily on webinar sessions.

The issue applies to some people and not others but the root of the issue if is the problem is to turn back on Windows Cleartype font or disable Hardware Acceleration which is for your Video Card. The issue sounds like it is so please turn on your Cleartype font. https://www.nytimes.com/2016/09/21/technology/personaltech/get-sharper-text-on-your-windows-screen.html

Contact WebEx Support : cisco.chromestore@gmail.com or visit their support page for tools and articles : https://support.webex.com/MyAccountWeb/supporthome.do as is listed on their Extension Page : https://addons.mozilla.org/en-US/firefox/addon/cisco-webex-extension/

You could try the 7min fix if it works : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

Reinstall with Current Release Firefox 59.0.1 with a Full Version Installer
