Shape, which shows the additional dots

Open attached document in current master. Make sure, that in your settings neither OpenGL nor Anti-aliasing is enabled. Notice, that the custom shape has additional dots left-top and right-buttom.

It has been OK in

Because it had been OK three weeks ago, I do not think, that it is a direct duplicate to bug #37559. But it might be related.

Comment 3 Heiko Tietze 2016-07-26 09:41:10 UTC
I get the artifacts at the pages pane but never on the view. So half-confirmed. It depends on anti-aliasing, when this feature is checked (which is on by default) the will-o'-the-wisps are gone.

Similar issues have been reported in bug 101032 for 5.2. Duplicate?
Comment 4 Regina Henschel 2016-07-26 09:53:48 UTC
There are problems with additional points, which are drawn on the page pane and in pdf export. And these additional points should be removed. But this issue is about the problem, that I see the points in the normal working area, if I use a _current_ 5.3 build. Which version do you have used? Perhaps the problem is specific for Windows?

Regression introduced in range 7289a140fc68dc898ba2b2357cc960968195f236..766524b13b3e69cc16cf19b826f62222d7f15ea5
Comment 8 Aron Budea 2016-09-17 00:30:42 UTC
Xisco, that range points to somewhere around 5.1 branch point.

I bibisected with Nortbert's recent 5.3 repo, with antialiasing turned off.
With antialiasing on, I get the extra points even from the first commit in the repo (5b168b3fa568e48e795234dc5fa454bf24c9805e).

Armin, bibisecting points to your commit:

Can you please take a look? Thanks!
Comment 10 Armin Le Grand 2016-09-22 08:02:59 UTC
This is an old error which comes from a BugFix originally from Thorsten, problems with the BoundRect of rotated objects in slideshow. It's in EnhancedCustomShape2d.cxx, commit f64ef72743e55389e446e0d4bc6febd475011023. It exists since 2010 and I was always unhappy with that 'hack' (as named in the comment in the cxx file). It does not only show, but is in the way for numerous things - geometric changes, 3D conversion, ...
Thus I have this on the radar but did not manage to recreate the original error yet.
Comment 11 Armin Le Grand 2016-09-22 08:11:16 UTC
Going back to the description and screenshot from comment 1 I would say it's the mentioned #37559. I checked the bibisected change, that is for pattern fill and should not add points to CustomShapes (which have no pattern fill)
