Screenshot of the header buttons after scrolling

With LO 6.4, "Internal Paths" are added to the Tools > Options > LibreOffice >
Paths dialog, and as a result the content is usually wide enough that
horizontal scrolling is needed.  When I use the mouse and the scroll bar at the
bottom of the dialog to scroll, I see black vertical lines showing up on the
header buttons.  When I scroll back, there are more of these lines on the
headers.  Clicking on the header clears these artifacts, but scrolling will
make them appear again.

Screenshot is attached.

I start seeing them from 6.4.0 beta, the first time I looked at this new
"Internal Paths" feature.  I can still reproduce in 6.4.0 rc1 now.
