Summary0003522: Save Image creates incorrect result with transparency
DescriptionHello,
if you use [b]tools -> Save Image...[/b] using a model with transparencies, you get the wrong result. All transparent objects are places over the rest objects, even if the are behind, so the resulting image is wrong.
I attached an example of a transparent box with an object inside. The wall of the box a placed wrong.

maxv's FC info is incomplete with revision number unknown. Obviously he didn't install FreeCAD from one of the two preferred methods for Ubuntu & derivatives.

This has been already discussed in the forum. The report author should have searched the forum first. I won't search for topics myself I have better things to do.

I can't reproduce it with:
OS: Windows 7
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.14888 (Git)
Build type: Release
Branch: master
Hash: 93f06f82560820469b63939b35557bea4dffa2e9
Python version: 2.7.14
Qt version: 4.8.7
Coin version: 4.0.0a
OCC version: 7.0.0
Locale: German/Germany (de_DE)

But the problem could be related to the OpenGL driver or Qt4 which is known to cause problems here and there on modern Linux systems. If there is a chance then it would be good to use a build that uses Qt5.

@maxv can you try reproducing this issue on the Qt5 appimage for 0.18dev (https://github.com/FreeCAD/FreeCAD/releases/tag/0.18_pre)
