@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 Version: 6.3.0.0.alpha1+ Build ID: 92b0b8d78d69bd917842b09af7888b402144baeb CPU threads: 4; OS: Mac OS X 10.14.4; UI render: default; VCL: osx; Locale: fr-FR (fr_FR.UTF-8); UI-Language: en-US Calc: threaded 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.

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.
