I've also experienced this with a published desktop running in windowed mode, where a large part of the desktop is black, but once I resize the desktop window, the black disappears and returns to normal.
I removed the vGPU profile from a XenApp server and booted it without GPU (None) and haven't been able to reproduce the same error on that server. Not sure if it's related to the drivers or vGPU profile.
My setup is:
- HP Proliant DL380 Gen9 servers
- 2 NVIDIA M10 cards in each server
- XenServer 7.12
- XenApp 7.14.1
- Windows Server 2016
- Provisioning Services 7.14
- StoreFront 3.12
- Citrix Receiver 4.9
- NVIDIA-GRID-XenServer-7.2-384.73-385.41 drivers
- NVIDIA License Server 2017.08-0001.
- NVIDIA Virtual Applications licenses (vApps)
- XenApp servers have 4 vCPU and 48GB RAM
- M10-8A vGPU profile for XenApp servers
Does anyone have any input on this?

According to the discussion threads Citrix have confirmed that it's a problem. There's a private hotfix (LC7875) that is available for XenApp 7.14.1 (which I'm using). I will request it though a support case. Citrix is working on a permanent fix for the masses in a future release.
Thanks again for your help, you're a lifesaver.
