[Resolved - sorta] Display quirk in Windows Conda-Python3-Qt5 version

[GeneFC]

I have been trying to use the "conventional version" of FC along with the new Conda-Python3-Qt5 version. I have not found any problems, but I have seen an unexpected quirk in the main window display.

First, the two versions I am using:

Conda

OS: Windows 7
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.15619 (Git)
Build type: Release
Branch: master
Hash: 7d8e5662648b794b5c93e28835a2bf5c1fddffec
Python version: 3.6.6
Qt version: 5.6.2
Coin version: 4.0.0a
OCC version: 7.3.0
Locale: English/UnitedStates (en_US)

Traditional

OS: Windows 7
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.15619 (Git)
Build type: Release
Branch: master
Hash: 7d8e5662648b794b5c93e28835a2bf5c1fddffec
Python version: 2.7.14
Qt version: 4.8.7
Coin version: 4.0.0a
OCC version: 7.2.0
Locale: English/UnitedStates (en_US)


What I am seeing is shown in the attached figures. The model is extremely simple and consists of one sketch and one pad. I am using the same configuration files for both versions of FC.

The conventional version looks completely normal; the same as it has looked for a long time. The Conda version, on the other hand, is missing a boundary line at the interior corner of the object. The shading looks correct, and every other property appears to be normal.

I tried various adjustments in the Display Preferences, with no impact. I even completely removed my configuration files, again with no impact.

If I make the object partially (70%) transparent (ctrl-D) it can be seen that the missing line is really there, but it seems to be overdrawn by the adjoining faces.

I do not know if I am making some sort of mistake, or if this is a small bug, or perhaps even a "feature".

This is all done on a simple computer system with built-in Intel graphics. I am using the latest available driver from Intel, but I think it is more than a year old. No recent changes at all.

Looking for any advice.

I can confirm this behavior. Linux doesn't show this behavior. Maybe a problem with coin3d.

Can you upload the model? I want to check it on my system:

OS: "Fedora release 28 (Twenty Eight)"
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.15576 (Git)
Build type: Unknown
Python version: 2.7.15
Qt version: 4.8.7
Coin version: 3.1.3
OCC version: 6.9.1.oce-0.18
Locale: Polish/Poland (pl_PL)

Sorry, I did not think the model would be interesting.

Thanks! It's not interesting , but gives 100% guarantee that we see (or not) the same error. On my linux box it works fine - the edge is where it's supposed to be.

Maybe a problem with coin3d.

I have close to zero understanding of Coin versions, Qt versions, Pythons versions, OCC versions, etc. However, it appears that Coin 4.0.0.0a is the only thing unchanged between the Conda and the traditional FC versions.

+1, me too is having this problem. Any edges on concave joints are invisible. Made me assume that fusion wasn't working at some point.

The version is the same but the sources are different. The build is done with cmake and sources are from a recent commit. (So not an official version) I guess this is what the "a" revers to. This is true for many other libraries.

So the best you can do is report this to the coin project. Maybe someone of the coin devs know what's the reason for this problem...

The edges are there only the visualization is not correct.

Did we have a similar problem already?

Not wanting to put a spanner in the works but am I the only Windows user who does not experience this display problem? I've tried deleting my config files to ensure that my specific Display Preferences were not enhancing the view but it still displays fine with new user settings. I've also gone back to build FreeCAD_0.18.15468_Conda_Py3QT5-WinVS2015_x64 to check if it was faulty back then and it displays fine on that too.

Hi
I also noticed this phenomenon but it did not make me fall from my chair,
I compared it to the same phenomenon that makes me unable to click a sommet of a sketch returned in Z minus, to see this sommet hide behind an existing object.
But I get around this by going in wired mode
