black screen during logon (= no logon feedback to user)
this one is annoying. While the user is logging on to the desktop, the ICA client only displays a Black Window, untill the user is logged on.
Citrix forum thread here :
best workaround until citrix delivers a server side fix : disable citrix enhanced logon feedback. Citrix KB here , regkey is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Logon\DisableStatus (64 bit os)
server hanging during shutdown
known, fixed issue. Servers hang during a shutdown, which is risky with sheduled reboots at night.

Progressive Compression causes flickering in a published internet explorer
from the citrix forums :
1. Obtain an experimental private fix from Citrix Technical Support that will disable Off Screen Surfaces from an ICA level. This can be obtained by contacting Citrix Technical Support (if you have a support agreement) and referencing Citrix Problem Report #236384. At this time, we have a fix for XenDesktop 4.0 available and other products would require development of the fix as required.
Or
2. Disable the Off Screen Surfaces feature from the client side by changing the EnableOSS registry entry located under:
HKEY_CURRENT_USER\Software\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\Thinwire Graphics\
