[Solved] Black screen - I can't run any project

Postby greatd » Tue Jun 11, 2019 8:54 am

Hello,
I have the same issue like described on here -> https://forum.freecadweb.org/viewtopic.php?t=36087

OS: Windows 7
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.16117 (Git)
Build type: Release
Branch: releases/FreeCAD-0-18
Hash: dbb4cc6415bac848a294f03b80f65e888d531742
Python version: 3.6.6
Qt version: 5.6.2
Coin version: 4.0.0a
OCC version: 7.3.0
Locale: Polish/Poland (pl_PL)

.17 version was working well, how to solve that problem?

... and how about the hints given in there? E.g. trying latest 0.19, changing GC driver?

I just checked how it works on .19 version:

The only difference between .18 and .19 versions is that in newer one only workspace is black, while .18 is completely black.
I've tried to update my drivers but it doesn't really help.

Qt version: 5.6.2
You must be compiling against the old lib pack. Sgrogan in the last post of the topic you linked to is the one who compiled the Windows builds. He link to the downloads page for 0.19, one of the files "FreeCADLibs_12.1.2_x64_VC15.7z" is a newer lib pack. It uses QT5.12.1 and was compiled with VC15, you may need to update your VC version, sgrogan will know as other may also.

I don't think so, the link should suffice.

Can you try to uncheck Preferences->Display->Use OpenGL Vertex Buffer Object.

Any chance this has something to do with it?

Thanks for the quick reply. Unluckly, no way, I also updated last display drivers but it doesnt help with the version above...

Instead I tried last Conda Build (FreeCAD_0.19.17108_x64_Conda_Py3QT5-WinVS2015.7z) and this works perfectly...

Code: Select all

OS: Windows 7
Word size of OS: 64-bit

Version: 0.19.17108 (Git)
