Description peter.carle 2020-10-26 21:31:18 UTC

Description of problem: 

Attempting to use videoconferencing applications such as the Zoom Linux client or the Microsoft Teams Linux client within F32 in a Windows 10 VM running on Virtualbox causes massive stuttering that makes calls unworkable. 

I have not tested whether this is an issue on a bare-metal Fedora installation, but it does occur consistently when running within Virtualbox.

Please note that running a videoconference application within a VM itself is not the cause of the problem. This setup worked fine up until the latest update to mesa. 

Specifically, the updates were to the following mesa packages:

-mesa-dri-drivers
-mesa-filesystem
-mesa-libEGL
-mesa-libGL
-mesa-libgbm
-mesa-libglapi
-mesa-libxatracker
-mesa-vulkan-drivers

The update would have been sometime around October 19th, 2020. 

Version-Release number of selected component (if applicable): 20.1.10-1.fc32

How reproducible: Consistent


Steps to Reproduce:

1. Install Zoom and/or Teams client (even watching YouTube may work poorly, though. Haven't tested that.)
2. Attempt a coherent conversation
3. (Optional): Attempt steps 1 and 2 within a Virtualbox VM

Actual results:

Normal conversation.

Expected results:

Stuttering that makes a coherent conversation exceedingly difficult.

Thanks!
