As we just found out on IRC today: this only happens if breeze is configured to draw a frame around dockable panels. Maybe this helps debugging and fixing it.
Git commit c1d9becda259c0df58b1447b69f573b6ef13bfa1 by Elvis Angelaccio. Committed on 21/01/2017 at 22:38. Pushed by elvisangelaccio into branch 'Applications/16.12'. informationpanel: don't change color of scrollarea's viewport This code was added a long time ago in b1c9b5126d, but the commit message doesn't explain why. If we remove it nothing seems to change and we fix the ugly background on the scrollbar when Breeze draws a frame around dockable panels.
