Screen lag issue with PCoIP on dual monitor

I ran into an issue, that I haven't seen before, with a customer. Big thanks to Karl for helping me out with the solution to this one. Basically the issue is that when you are using a Multi-Monitor system, and you want to drag a windowed application from one monitor to the other. The screen has "Lag" meaning the windows is jumpy or glitchy as you drag from screen 1 to screen 2. This issue can occur when you have;

  • Windows 7 (32 or 64 bit)
  • Virtual Machine hardware 8
  • VIEW agent 5
  • A multi-display client
The resolution to this is to simply add an entry into the *.vmx file of the VM. The entry is to be added to the end of the VMX file and below is the entry.

mks.poll.headlessRates="1000 100 2"
