smoothGraphMarkers=True does not stop Graph Cursor Flicker

[viScience]

I have a xy graph where the cursor labels flicker every time the graph is updated.  I have tried setting the smoothGraphMarkers=True

switch in the Labview.ini file but it does not make any difference.  I have the smoothupdates graph attribute set to true and have experimented with disabling graphic card acceleration.  Nothing seems to help.  I have been told that this started to happen when we recompiled the application from LV8.0 to LV8.2.  BTW, there are not any graph property nodes in the loop that could be causing a refresh.  Thanks.

sachsm,

Are you also setting the Cursor.Allow Drag property of each cursor to FALSE?  This can done by either using a property node or by right clicking on the cursor and unchecking Attributes»Allow Drag.

Without this setting cursors are redrawn at every update just in case they have been moved.  By disabling the ability to move them along with the other settings you have already mentioned LabVIEW is able to render the cursors as part of the background bitmap and then update the screen all at once.
