Key Resolved Issues
Blanking Screen Bug Fix
12553 - VM driver release 2.3.4 (apex2800-2.3.3-rel-31865.exe) fixes a screen blanking issue that some users experienced when virtual displays were offloaded.


Key Known Limitations

9562, 9806 - Reports of a server "PCIe Training Error" message during server boot on some platforms using Intel Ivy Bridge Processors. Please open a ticket with Teradici.  

Reports of ESXi Purple screen (PSOD) in circumstances when operations utilising the VMware fast suspend resume (FSR) functionality are completed on ESXi hosts containing virtual machines with/without APEX drivers. These operations include but are not limited to Storage vMotion, and/or hot adding a CPU to a virtual machine. This is still under investigation. 

10664, 10625 - Caching is not supported on multi-display PCoIP sessions. When more than one display is connected to a VM, the caching is not working, meaning bandwidth utilization will stay the same as with APEX 2800 drivers 2.2.

6622  - Lower frame rates when using a VMware View software client. Occasionally, with certain workload types, the software client output frame rate will be slightly lower when a display is being processed by APEX. Teradici PCoIP zero clients are unaffected.
In some occasions, you might experience a reduction of frame per seconds in a GPU Pass through environment (vDGA).

The above known issues are under investigation. Please subscribe to this knowledge base item to receive updates.
