Description
Various graphical problems on special programs, such as black/white screen problems, color problems, truncation problems, etc.
This problem only occurs on VDAs with automatic resolution adjustment; these problems do not occur with fixed resolutions.
Environment
Caution! Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.
Resolution
Configure fixed resolution for ICA sessions.
Example:
Set a fixed resolution by specifying .cx and .cy values in the registry.
Note!
(Please change [xxxxxx] in the example registry value to the actual value).
