Graph Panel flickers while moving move pointer in the page and graph dissappear

I am having a trouble with displaying a list of graph panels in a dashboard. When the mouse pointer is being moved anywhere in the page, all the graph panels flickers and graph displayed disappear. This happens randomly and its frequency of occurrence is less. Kindly suggest some idea/tips to get rid of this issue.

You are the fist to experience this, we are unable to replicate. What browser and OS see you running?

Thanks for the reply torkel.
browser : chrome
os : ubuntu-14

strange, that is the same setup I used to run a while a go. Try updating chrome, ubuntu or graphic drivers
