UI Rendering Issues in Excel and Outlook 365

[SchwarzC]

Hello everyone,

We've had reports from several users that the UI in Excel and other Office apps like Outlook isn't rendering properly. I've attached a screenshot so you can get an idea of what we're seeing. I suspect this might be related to hardware acceleration, as we're using NVIDIA GPUs in our environment.

Here's a quick overview of our setup:

• Horizon 8 2212.2
• Windows 10 22H2 (September patches applied)
• FSLogix (latest version)
• AppVolume 2406
• DEM 2406
• NVIDIA A16/NVIDIA A2 GPUs
• Shared Direct and Shared Passthrough GPU assignment policies
• VMs spread across GPUs for best performance
• Latest NVIDIA drivers (16.7) on Hosts and 538.67 on Windows
• BLAST only with Windows Devices as our underlying OS

Interestingly, this issue isn't affecting all users—just a few here and there.

Has anyone else experienced something similar, especially in environments with shared GPUs? Any tips or known fixes would be greatly appreciated!

Thanks in advance!

Hello @SchwarzC,

what type of codec do you set on client?

[SchwarzC]

We left everything on default

So

Allow BlastCodec Decoding

Allow H.264 Decoding

ALlow HEVC Decoding

Allow AV1 Decoding

On the VDI we see the following (HEVC 4:2:0)

Please enable HDR and check, in my case with GPU works good.

I'm not sure this is a hardware acceleration issue.

You said this issue is impacting users intermittently?  Does the issue go away when the user logs out and logs back in?

Are you using Office 365 or a volume-licensed copy of Office?  If you're using Office365, how are you managing updates?
