image thumbnails to not display, arch linux webex client

[pmullen]

Images fail to load on Linux thick client on my arch linux install.  If I click on the square that would be a thumbnail, a new window pops open with the image inside, but the "thumbnail" is a grey box with a spinning circle, trying to load.  Version is 42.1.0.21190.

I have narrowed the issue down in current_log.txt to be related to the message:
"MessageBuilder.cpp:328 getSharedContentPreviewDiv:Cannot create HTML div for thumbnail."

I will be happy to provide full logs to relevant parties.  I assume it's probably related to some graphics library I'm missing, maybe?, because I have talked to others using the same version client and their thumbnails display fine (Linux Mint 20.1).

Thanks,

I'm also using ArchLinux. I've spent some time debugging with strace and various other tools.

It would seem that my archlinux package is missing "png" format in this folder:

/opt/Webex/lib/plugins/imageformats

I've reached out to the AUR package maintainer.

The Webex app for Linux is only supported on Ubuntu 18.04/20.04 and RHEL 8.2/8.3, see https://help.webex.com/9vstcdb/

Maybe it is an issue with arch Linux and your're just lucky with Mint..

FYI Linux Mint is Ubuntu with a different windowing system (Cinnamon vs Gnome) and a different software manager.

I'm sorry, but a Linux distribution is really nothing more than a collection of default libraries and applications.  If I know what library is missing, I should be able to install it and get it to work on any distribution.  Do you know what library(s) is needed to display the thumbnails?

Thanks,
