Sketch lines all go black
I'm using 0.19
OS: Windows 10 (10.0)
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.19.24267 (Git)
Build type: Release
Branch: master
Hash: b2ca86d8d72b636011a73394bf9bcdedb3b109b7
Python version: 3.8.8
Qt version: 5.12.5
Coin version: 4.0.0
OCC version: 7.4.0
Locale: English/United Kingdom (en_GB)
Every now and again when I am doing a sketch all the lines and points change colour to black. Going out and back in to the sketch puts them back to normal. Am I doing something that can easily be reversed by mistake or is this a bug I should report?

Re: Sketch lines all go black
Neither of these. I remember Werner saying that something is running out of resources. Reopening sketcher or even restarting FreeCAD usually helps.

Ta Chris, that was what I found going out and in again clears it up.
This computer has 12 cores and 64gb Ram though so not sure what resources it needs Is the code base 32bit?

Re: Sketch lines all go black
As you can see from your FreeCAD infos, you use a 64-bit FreeCAD. I don't think it is the hardware resources, it is rather something in one of the used libraries such as Qt (I don't know which library finally handles Sketcher's 3D view).

Re: Sketch lines all go black
I had the same problem on similar machine (occasionally) and the solution was the same, so glad that it isn't only me
As for the cores... apparently it is CPU clock speed that matters more than a numebr of cores, for 3D CAD work:

Re: Sketch lines all go black
This has been reported in French subforum by several users but we never could narrow down what causes this issue... Maybe Coin or OpenGL
Re: Sketch lines all go black
Yeah it is really random. When it starts happening it keeps on doing it but most days it does not ever happen. I've not even been able to workout what I was doing just before. If I ever do I will report it. Otherwise its just one of them wrinkles I'm more than happy to pay for a program I'm enjoying
Re: Sketch lines all go black
I'm happy there is now a thread in the main subforum, but I'm afraid there is indeed much we can do while we have no way to reproduce the issue.
Re: Sketch lines all go black
Another user here that's experienced it. Glad I'm not alone at least ! If it happens to me in any sort of repeatable fashion I'll report but by the sounds of it this is an elusive creature.
