Steps: 1) Open Impress 2) Draw a shape 3) In the sidebar area content panel, drag the transparency slider and notice that all content panels in the sidebar refresh constantly during sliding. The behaviour isnt as bad in Writer, as the refresh only seems to happen at the end of the drag. Not setting this to bibisect as 5.1 replaced the spinbox with a slider.
