[Sketcher] Arrow heads disappear on hiding the grid

[FBXL5]

Do you still get this in more recent dev versions?

Yes. With this weekly build

Code: Select all

OS: macOS 10.16
Word size of FreeCAD: 64-bit
Version: 0.21.0.32532 (Git)
Build type: Release
Branch: master
Hash: 20e44eba50e1365b9e7bb9c5c244afe96a627a28
Python 3.10.10, Qt 5.15.8, Coin 4.0.0, Vtk 9.1.0, OCC 7.6.3
Locale: C/Default (C)
Installed mods: 
  * freecad.gears 1.0.0
  * fcgear 1.0.0
  * Render 2023.2.2

  * fasteners 0.4.55
  * sheetmetal 0.2.63
  * Help 1.0.3
  * Curves 0.6.8
  * Assembly3 0.11.4

the arrows behave like this (have a look at the dimensions as well):

I skipped the back views for One pass since they match the correct front views.

I saw a mention of this on the Sketcher_Preferences page.

The description according to the Transparent objects setting is still valid, but it seems to be independent of the grid now.
@chrisb and @adrianinsaval can you still reproduce this behaviour?

With adrianinsaval's Linux system and Chris' and my 3 macOS systems it seems to relate to unix-based OSs.
"There is another preference that has an influence on sketches." should better read "... that may have an influence..."

Yes and even worse: If I have grid enabled plus One pass everything is ok. If I then switch the preferences while in Sketcher, the arrows disappear even with grid enabled:

Thanks.

I can't reproduce on Linux either (same computer). So perhaps it is hardware related.

What should cause hardware to display arrow heads from one direction but not from the other?
If it is related to depth or visibility calculation I would rather think it is software causing calculation errors than hardware.

Are there known issues related to mac hardware?
Especially
- 2012 MacBook Pro i7 with NVIDIA/Intel graphic card
- 2015 iMac i7 with AMD graphic card

I'm still curious if adrianinsaval's linux machine still reproduces this imperfection.

OpenGL ?

[chrisb]

OpenGL ?

I don't think so. I tried with SoftwareOpenGL and it's the same.

[FBXL5]

OpenGL ?

Neither OpenGL setting has an impact.

Hello, did you test it with a clean setup?
I mean by deleting user.cfg to get a reseted preferences and parameters.

Yes, with a fresh .cfg file I found out that it depends on the Transparent objects setting back in August.

setting back in August.

Ops, I missed the other page of the thread, sorry for the noise.
