If only Microsoft monitored its posts and reached out to me as a gesture of good will... To that end, I have support tickets opened with their enterprise support. Doubtful we'll find resolution.
Other than the issue of not having SlimCore access when using Omnissa VDI on IGEL (Linux) endpoints using Windows gest OS, mirroring is permanently enabled by default and there's no "unmirroring" in VDI. Not only is my video mirrored, but it mirrors the background too. -you can imagine how bad this would be if you have branding text applied. All others in the meeting will see your video unmirrored. Mirror settings are simply missing in VDI. Hopeful MS Support can pull a rabbit out of their hat with some sort of registry key or config file modification.
