This is a known issue related to OpenGL. The issue is due to an incompatibility between the Qt's webview and the OpenGL installed on the user's system. Engineering has investigated the cause, and stated this will be resolved in the next GA release of ARD. The ARD 3.0 release is targeted to be out around Q3 of calendar year 2019.
As a workaround go into the ARD Settings Dialog window, and change the Editor Type, from the default value of "ACE Editor" to "Plain Text" and save the settings.
