Fix Graphics Problems

Poor implementations of 3D graphics acceleration on some PCs can cause graphics drawn by WebFOCUS Visual Discovery to be incorrect or corrupted. This happens most often on older laptops. You can often correct this problem by turning graphics acceleration off for the system. Typically this is done by:

  1. Go to Display Properties (from Control Panel or by right clicking on the desktop and choosing Properties).
  2. Select the Settings tab.
  3. Click the Advanced button.
  4. Select the Troubleshoot tab.
  5. Move the slider labeled Hardware acceleration to None. (Possibly something between Full and None may work as well.)

You can turn off hardware graphics acceleration just for WebFOCUS Visual Discovery by changing the configuration file for WebFOCUS Visual Discovery.

Add a new entry to the appSetting section. This will typically contain this initially:

<appSettings>
          <add key=”CommandTimeout” value=”30”/>
          <add key=”SkipRowCount” value=”false”/>
</appSettings

Add this line to this section:

<add key=”UseGenericGraphics” value=”true”/>

The section will now look like this:

<appSettings>
          <add key=”CommandTimeout” value=”30”/>
          <add key=”SkipRowCount” value=”false”/>
          <add key=”UseGenericGraphics” value=”true”/>
</appSettings

The value may be false or 0 to cause acceleration to be used.
