Fuzzy Citrix

This may sound strange but we have a Tess Citrix User whose Citrix is fuzzy.  When the User lands on the first Tessitura Screen (after logging in) the screen is blurry.  We have tried using other browsers, checking other web pages totally unrelated to Citrix, restarting, checked the monitor and screen, itself, etc., but nothing makes a difference.  It's this one screen/Tess Citrix Page that is blurry/fuzzy.

Has anyone else run in to this issue?  If so what was the resolution?
