Chromium Browser - Title bar and panel disappears while playing flash videos

Hello All,

I am new to the OpenSuse and I used it for mostly for browsing and playing multimedia content.
I have recently installed OpenSuse 13.2 and installed Chromum browser.

Whenever I play some YouTube video or flash videos from other websites, the tittle bar of the windows and panel (task manager panel) suddenly disappears.
Also the Kickoff Application launcher doesn’t open up. I can not do any other activity. The screen just freezes.

However this doesn’t happen with Firefox. The videos play smoothly without affecting anything.

The only way to go back to normal is to restart OpenSuse forcibly using hardware power button.

I really appreciate your help and time in this issue.

Thank you.
