This page relates to graphical issues and rendering problems in Omniscope Classic. (It does not relate to Omniscope Evo, which uses a web-based interface in your modern browser such as Chrome.)

Note that the first thing to try in the event of seeing graphical or other problems in Omniscope is to ensure you are using the latest ROCK version of Omniscope, as the problem may have already been resolved.

Graphical glitches

If you are experiencing graphical glitches and artifacts in some of the Omniscope Classic views (especially the web-browser-based Web View, please follow the steps below to resolve the glitch by setting the system property "sun.java2d.d3d" to "true". This property is normally set to "false" by default to fix potentially slow rendering when making selections in the Graph / Scatter view.

Open "" which is in the Omniscope program folder, normally found at "C:\Users\<yourname>\AppData\Local\Visokio Omniscope app" or "C:\Program Files (x86)\Visokio Omniscope".

Find this line: 


Replace it with this line:


Ensure no other line exists. If it does, you will need to combine the two.

Save the file.

Restart Omniscope.

If the above still does not fix, you may also want to try the following variations.

ADDITIONAL_JVM_ARGS=-Dsun.java2d.d3d=true -DuseAcceleratedCompImage=false




Try these individually, or combinations thereof.

If this doesn't help, try these more exotic options:




ADDITIONAL_JVM_ARGS=-Dsun.java2d.opengl=true -Dsun.java2d.xrender=false

If you find a solution, please share a summary of your problem with the option needed as comments here. You should use the minimum options needed to solve the glitch.

Connecting to a remote server

When connecting over Remote Desktop or Splashtop, you may find that some windows appear blank. This has been seen before to be caused by colour depth. Try changing the connection options - for example changing colour depth from 32bit to 24bit - or changing the connection route such as using RDP instead of Splashtop.
