You might run into an issue where you load FE from Citrix and it starts flickering randomly as well as not showing your mouse on the screen. This is especially common with hardware setups where you are using multiple displays. To fix this, you need to do the following:


1. Right click on the blue Citrix logo in the taskbar item-tray:


2. Select Advanced Preferences

3. Select High DPI
​4. Make sure that this is set to "No, use the native resolution"


You may need to restart Citrix after doing this, but the issue should go away after this configuration change is made.
