UCI Touch Panel response is slow or lagging.


  • High number of control elements in the UCI that may effect processing resources
  • Image resolution is too high for touchpanel resources

Solution | Workaround

  • Replace any video preview windows on the UCI with the Media Display released in Designer 9.2.1
  • Reduce any multi-page UCI's to a single UCI with multiple layers
  • Reduce the overall number of control elements in the UCI
  • Avoid excessive TSC graphic asset scaling up or down in size. Graphic assets should closely match the resolution of the target asset resolution.  
    • Generally background images should be scaled to closely match the resolution of the panel.
    • Button backgrounds and icons too should generally match the resolution of the button object.
  • Set the UCI's Swipe Disable to Yes and Enable Button Swipe to No if possible
  • Avoid multiple UCI Layer Visibility Transitions happening at the same time
  • Reduce the number of active VU meters in the UCI to lower the data received by the TSC panel
  • Avoid using VU Meters using the Segmented Meter type
