We have the issue with Citrix Receiver 4.5 or higher that dragging windows from one screen to the other screen is very slow .When using receiver 4.4 there is no issue.
Already an forum topic on citrix without a fix:
https://discussions.citrix.com/topic/381578-receiver-45-dual-screen-slow-on-thin-client/
Power options are already on hight performance.
Does anyone have a fix for this?
