I just installed FreeCAD 0.18 on a linux mint pc from the official ppa-s.
My problem is, all models are black upon creating a new model or loading an existing one. Here is a screenshot from the Engine block example included with the FreeCAD installation.:
I suspect it has something to do with libpng but not sure and don`t know how to fix it. App images don`t produce such error. Attached a log file.

Re: All models are black
Why? It has nothing to do with 3D graphics, and this is clearly a graphics issue.
That's an utterly obsolete version of OpenGL (current is 4.6 - I'm using 3.1 myself), I'm guessing you have some kind of very low power, probably old graphics chipset?AvgJoe wrote: ↑Wed Apr 24, 2019 7:00 pmCode: Select all

Can you post details from them? I suspect your AppImages are not of FC 0.18 but 0.17, and that they're based on Qt4 while 0.18.1 is based on Qt5.
Re: All models are black
it is possible that you have created an invalid solid, although it doesn't sound like it. Please post a FreeCAD file that displays this issue.
why would you be running a 32bit version, why not 64? If your system is truly on 32bit it must be truly pathetic. You can get truly pathetic computers for free from the garbage dump that are still 64 bit. How long has it been since the Athlon64 bit came out? Are you running in a virtual machine? Please post your hardware details.

Relevant system information:
LENOVO ThinkCentre M57
VGA compatible controller: Intel Corporation 82Q35 Express Integrated Graphics Controller
glxinfo -B:
Intel Open Source Technology Center
Mesa DRI Intel(R) Q35 x86/MMX/SSE2
OpenGL version string: 1.4 Mesa 18.2.8
The installed version of 0.17 worked for a while but than produced the same error. The reason why I switched to 0.16/0.17 app images which are fine. Couldn't`t test a 32 bit 0.18 app image yet.

Re: All models are black
please test both 0.18 and 0.19 appimages as well.
Alone you go faster. Together we go farther

Re: All models are black
The FreeCAD 32-bit 0.18.16093 (Git) AppImage works fine. But it was built from freecad-maintainers/freecad-daily.
Re: All models are black
The trend we see here is that some Intel graphics have issues with FreeCAD compiled with Qt5. The 0.18.16093 (Git) AppImage is built with Qt4.
Re: All models are black
The 0.17.13541 had the same issue.
