Blank Icon(looks like a white page) for applications running in VDI

John Newman 5

User's image

Hello, my organization just moved to Azure. We are still determining what exactly our infrastructure will look like going forward and basically did a lift and shift. Currently, our users are using VDI pool to work in applications inside a secure environment from their work computers. They use Azure Virtual Desktop Preview to do so. A major problem we are having is most of applications open and running in the VDI show up in blank in the task bar. Please see attached image. It is making work difficult as we are unable to switch back and forth from apps easily.

Hi John,

We are experiencing the same problem with Azure but it is only happening for some users so it has been a challenge to diagnose. I have checked multple times our icons are set to the correct path.

Have you come across a solution to the problem at all?

Hello @John Newman

Thank you for reaching out to the Microsoft Q&A platform. Can you please check the behavior with the latest MSRDC version? or Windows App
Also, make sure that those end point devices have access to all required endpoints as documented Required FQDNs and endpoints for Azure Virtual Desktop | Microsoft Learn

Sometimes proxy configuration etc. block proper access.

How did you publish the remote apps via AVD? Is the Icon path correct?

This is an example, you need to adjust it to your needs

Also seeing this myself currently after a UPN change for a couple of users.

Wonder if any one was able to get to the bottom of this at all?

Hi Oliver Soper/Stephen Akitt

Please use Windows App or MSRDC instead of the Azure Virtual Desktop preview app.

Also, make sure that those end point devices have access to all required endpoints as documented Required FQDNs and endpoints for Azure Virtual Desktop | Microsoft Learn

Sometimes proxy configuration etc. block proper access.

Was only affecting a couple of users. Icons path were correct for the published app and word would work fine but not excel for example

I could not right click the app on the users session to check the icon path in his session but was able to do this earlier when i logged in as the user and looked to be an issue with the local cache on his machine. I repointed the icon manually to the local icon cache and now loading correctly.
