When using Citrix Published virtual apps on a setup with 3 monitors with a resolution of "2560x1440" each and one of them is in portrait mode, the mouse pointer is shifted in the app and it is not possible to use it correctly. The mouse pointer appears to be about 5cm next to where it is shown on the screen. This does not happen when all of the monitors are in landscape mode.

Example




 

1. Set the Display memory limit" policy to 4,194,303 to fix this issues.
   • You should calculate the minimal rectangle that can hold the three monitors. In this case, it's the red one as below. The formula is 2560*(2560+1440+2560)*4/1024 = 65600KB, as you can see it's a little larger than 65536KB
