In Writer thin white lines remain between pages while scrolling from time to time, expecially before/after page breaks (see screenshot).
Steps to Reproduce:
(1) Open Writer
(2) Create new document
(3) Insert some text for more than a page
(4) Insert a page break
(5) Scroll forth and back until issue becomes visible
Rendering artefacts remain between pages as thin white lines while scrolling
Page borders are rendered without remaining rendering artefacts
User Profile Reset: No
OpenGL enabled: Yes
Issue was present in previous version of LO too. It seems better with current revision from master, but issue has not disappeared completely. Issue does not seem to be related to OpenGL.

@Thomas : not really sure what I'm supposed to be seeing here. I occasionally see a sort of grey line (rather than white) superimposed between the pages as I scroll down or up, is that what you are referring to ?
Forget that, I can confirm this with

I just had to make sure that several pages were filled.
What is the artifact on the screenshot? the white tinny line ?
Yes, in the case shown by screenshot there is one thin white line. Depending on scrolling there are situations with two or three of such lines too.

@Thorsten: is this still happening for you and if yes, on which macOS?
Setting to wfm, please re-open should this be persisting for you.

Yes, this still happends (from time to time). Maybe it is caused by current implementation of alpha blending. Discovered this issue on Linux/UNIX too in the meantime. Reverted the status to "new".
Thanks for double checking. If anybody discovers repro steps would be nice to share as I was unable to find any.

Thing is pretty common, have seen this on Windows too
