I upgraded from openSUSE 13.2 to Tumbleweed, by eventually wiping the drives
and starting fresh. After using Plasma 5 on Tumbleweed for a period of time,
sometimes 30 minutes, sometimes 5 hours, the panel will freeze, and eventually
programs will start freezing as well. The 13.2 installation had no such issues,
even when using the Frameworks5 repositories.

Reproducible: Always

Steps to Reproduce:
1.Run Tumbleweed
2.Use desktop as usual.
Actual Results:  
Desktop panel freezes. Effect is more noticeable while watching videos. The
video may loop over and over the last 3 seconds or so of play.

Expected Results:  
Desktop should not be freezing.
