Robot Framework + Sikulix capturing back screen

We are working on implementing testing automation using Robot Framework + Sikulix + CI(Jenkins). We want to execute the test scripts on a remote machine (slave) in master slave configuration using Jenkins. We are using the robot frameworks swing library to test the Java Swing applications.

Problem : The Sikulix scripts are capturing black screen on the remote machine and further failing with no image found error. The same scripts when executed manually on the slave works fine.

 It appears that the scripts are working fine if triggered manually with mouse click or enter keyboard input. The same scripts cannot find images (captures black screen) when triggered automatically using Jenkins or any other background trigger.

I have even tried triggering the scripts via a windows scheduler but again Sikulix captures black screen. It is somehow appears that RB + Sikulix for Swing Library can only work if triggered manually.

Please let me know if you need any more information.
