Reproduction steps

be sure to be in classic theme
run rapps
search for "build env", you will get one hit
resize the listviews header repeatedly in a way that will make the horizontal scrollbar start to appear, and end to appear, start to appear, and so on...

Observed result
at some point the scrollbars will not be drawn properly, but this does not always happen
