WebEx client freezes section of laptop screen when undocking computer.

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.

We are seeing this issue in our enterprise as well. We've also seen this issue appears when a user connects to VPN (regardless of docked/undocked) which leads us to believe it is triggered by switching networks and not a screen resolution change. When our users undock their laptops, they automatically switch from a wired to a WiFi network. Users that have "unplugged" their docks from the wired network connection have not experienced the issue.

So, that could be similar to our issue... when the user is docked they typically have a wired network connection available (at most of our locations) but when they undock they switch to WiFi.

 

Essentially the same situation.

Have you found an answer to this problem?  We are seeing the same thing.

We are seeing the same experience with several of our users.  A portion of the screen in the size/shape of the Webex desktop app freezes. Only resolution is to "end task" which not all users can do for themselves.  Please advise of the resolution.

Re: WebEx client freezes section of laptop screen when undocking computer.

I've encountered several instances of this issue in the last 30 days.

Issue
Approx 1/4 of screen shows transparent swath , Layer 0 (top layer over all other apps on desktop.)
Un-docking seems to freeze laptops, re-docking restores previous issue state.
Hardware: Dell 7480/90 models and C-docks involved, Wired or Wi-Fi
OS display scaling turned on , typical setup  Laptop @150% , Mon1 @ 100%, Mon2 @ 100%
*Observed setting scaling across all displays to 100% improves on performance and issue when docking / un-docking.

Also have 
1 Have performed Dell DCU on machines.
2 Uninstalled WebEx (via the OS' software uninstall method)

3 Run https://help.webex.com/en-us/WBX000026378/Meeting-Services-Removal-Tool
4 Rebooted

5 Reinstalled current version of WebEx from Cisco site.

Current status:

Over a week now and not seeing any repeats or new reports, have monitored roll-ups of WebEx and several minor updates have rolled out.

Happened to me once recently. There was a large black box where the app should have been. It corrected itself once I clicked the system test icon to bring the application to the foreground. Windows 10 + 39.9
