blur with glitches

Version:           git master (using Devel) 
OS:                Linux

Sometimes when the widget updates and the blur region changes, the translucent part dose not update. The widget will repaint properly after I move the mouse to the taskbar in the plasma panel. If I disable the cache the glitches disappear. I am using oxygen-transparent style. and kde-workspace d17dc35f704e4a7379ac618fb0de8547737eca3b

Reproducible: Always

Steps to Reproduce:
1. Open systemsettings
2. Select desktop effects

Actual Results:  
Part of the translucent widget does not update, like blur.png in the attachment

Expected Results:  
Should be like blur2.png in the attachment
