Hi,
The issue looks like a network issue rather than something Qt specific. My cold guess is that the remote X connection’s latency is higher than your List View’s update frequency. So the remote server starts to draw the widget and a new version is pushed before drawing is finished.
You can narrow it down by temporarily reducing the update frequency to, say, 15seconds. If the remote X connection displays the List Widget correctly, the network is the troublemaker.

Thank you. Same application works on local X server running 4 times at once and it is ok. I will try to reduce display latency
X-term and Kate works OK even on remote machine X server
