Virtual Backgrounds Arch Linux

Using Zoom version 5.16.10 on a Thinkpad with an Intel Core i7-5600U (4x 3.2GHZ) with Mesa Intel HD Graphics 5500 with Arch Linux (kernel v.6.6.6)

Zoom provides the option to select a virtual background without a greenscreen, but selecting any of the available options changes nothing, and upon reopening the options the selection has reverted to None.

Please advise.
