# – Troubleshooting: – #
Some users experience an odd visual bug with TomViz/Paraview. It typically has to do with a compositing setting for the (ThinLinc) window manager (xfvm). This is most likely the solution:

• Start a terminal, navigate to the home folder by calling
• cd $HOME
• then call the following command:
• xfconf-query -c xfwm4 -p /general/use_compositing -s false
• This changes a key in the configuration file.

Afterwards, a log-out/log-in of ThinLinc is required. Be sure to “End existing session” to fully refresh the window manager etc.
Once the client is launched, check the “Options” menu. Under “Options” there is a “Reconnect Policy” section. Make sure that the option: “Always ask how multiple sessions should be handled” is activate.

As an optional check do the following:

• Call the following command in a terminal from the home folder;
• grep “use_compositing” .config/xfce4/xfconf/xfce-perchannel-xml/xfwm4.xml
• which should then return
• <property name=”use_compositing” type=”bool” value=”false”/>
