Created attachment 156983 [details] 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.

It can also be reproduced in Linux with gen VCL plugin. This is actually a regression from the following commit, there are no artifacts before that (I noticed a bit of flickering, but that is probably not relevant).

I feel its a preexisting scroll+invalidate bug which didn't matter until we began using the headerbar in a different way
