Horizon 8 2111 Rotated Secondary Monitor Issue

After migrating from Horizon View 8.2 to Horizon View 8.4 we are seeing an issue where customers have a secondary monitor attached (to Teradici Zero Client) and rotated 90 degrees, when opening or moving windows on the secondary monitor it is very laggy and will fail to render all the pixels (see artifacts left over in the window and on the screen). When moving the window/application (like Word document) back to the primary monitor (portrait) the artifacts will follow by will disappear when the screen refreshes. We used to install the SVGA driver with the Horizon Agent, however, due to the vendor change we are now using the SVGA from VMware Tools. We have tried extracting the driver from older tools (not sure if there is a way to extract the driver from an old Agent installer) going all the way back to VMware Tools 11.0.5 and also tried using the VMware Tools SVGA driver from the latest VMware Tools 12.0.0 with no change in behavior. We have also tried rolling back our Zero Clients to the last firmware (21.03) in which the secondary monitor being rotated 90 degrees was working...nothing is resolving the issue. We will be opening a ticket with VMware, but wanted to see if others are having the same issue. We did see a post about applications performance issues with the VMware Tools SVGA driver, but as mentioned above we tried to manually update the Display adapter using various SVGA driver versions to no avail.

I don't have any updates. We are still running the provided work-around in a separate desktop pool to support the customers utilizing this monitor (rotating displays) configuration.

We are going through our change management process now to get approval to begin testing the 2203 agent. However. given that jhol5 posted that they were still seeing the issue after updating the Horizon Agent, we are expecting to still have to run a separate pool utilizing the supplied work-around. We are going to test to confirm of course.

We are using the same workaround. 

I have to say: This will work in 75% of the cases. We still facing the issue, that some users still getting artefacts from time to time and need a restart.

If users roaming the vdi session from one to an other zeroclient or from blast to PcoIP we see that the workaround is not working correctly.

Any updates by VMware?

Hi All,

Over the past week VMware and Teradici have worked together to come up with a work around for the artifacts showing when display is rotated 90 degrees clockwise. Please follow the steps below, we have tested this in our lab and if has resolved the issue.

  1. Connect via RDP or use VSphere Web Console. Check in Device Manager if Display Adapters has VMWare SVGA. If it does, disable VMWare SVGA
  2. Create the registry value HKEY_LOCAL_MACHINE\SOFTWARE\Teradici\PCoIP\pcoip_admin\pcoip.disable_svga_async_capture=dword:00000001
  3. Connect to a session and test 90deg clockwise rotated display

At the present time this is the only work around we have.

Has anyone tested w/ the 2206 View Agent yet? I see, in the Release Notes, that there were other display issues addressed, but nothing specific to rotated monitors + PCoIP.

The support recently informed me that this version should fix the issue, but with the same workaround we are currently using. 

Will try it right now.

We're not keen to move on from 2111 ESB version so we're waiting for an agent patch on that. Support said 2111.1 would fix the issue, but that won't be released until the end of this year for some reason :(. So, alternatively, we're testing 2106 agent in our 2111 environment. They said they will fully support that combination in case any other bugs. 

I guess, if that works, we will stick with that until a stable patch is released for 2111.
