Over the last few days, we have noticed that the Webex client will leave a frozen chunk of the screen where the app would appear if it were running in the foreground. We usually see this when a laptop is undocked from a docking station and the screen re-adjusts the scaling factor/resolution.
The 'frozen' section of the screen floats in the foreground over the top of anything else that is opened. For example, opening Chrome full screen will open behind the "frozen" chunk of the screen.
you can resolve this issue simply by opening the WebEx client (bring it to the foreground) and then moving or minimizing it. Killing the WebEx client with task manager also works as does a reboot.
Display drivers are up-to-date.
