We are having this problem with XenApp 5.5/Win2003/ArcGIS 10 and we have set it to 16-bit. So that does not seem to solve the issue. Any other ideas? If anyone is experiencing visual artifacts with ArcGIS 10.x (or prior release) on Citrix, reducing Application Color Depth to 16-bit color seems to address a number of these issues. (Citrix Access Management Console > Farm > Application > ArcMap > Properties > Advanced > Appearance > Colors > Set to 16-bit) Most notably, recently we found that Citrix clients running ArcGIS 10.0 / XenApp 4.x / Windows 2003 Server are unable to render the "ArcGIS Online" browser from within ArcMap. Reducing ArcMap color depth to 16-bit addresses this issue. * The issue does not surface with ArcGIS Desktop 10.0 / XenApp 5.x / Windows 2008 Server. I'll continue to post these "tips" as we run across them.
