Bug in Freecad 0.19 development cycle - desktop seen through grid

[arnn]

Hi, In the recent freecad development builds, my desktop shows through the grid. there is a transparency in the grid when grid is on, and the content on my desktop is seen through.
i am referring to freecad0.19 development build 20514 for mac os. have attached a screenshot showing the same.
i hope this is the right forum to post bugs.

It is the right forum, but you should attach your full FreeCAD info as described in the IMPORTANT forum rules linked above.

I can confirm that behaviour. Any transparent object (even pre-selected objects or datum planes) let the desktop shine through:

The problem seems to be related to the Qt version. Some time ago I built FreeCAD by myself using Qt 5.13 and that FreeCAD did not show the effect. However, currently I'm not able to build FreeCAD again, because that Qt-pyside2-Python3.8 mixture in Homebrew is a totally mess.

Looks like one of the "MacOS poorly supports openGL" bugs.

Maybe, but the problem has only existed since the OSX builds are created using conda.

Maybe, but the problem has only existed since the OSX builds are created using conda.

I don't think conda is the culprit. We had seen this sometimes long time ago in 0.17, perhaps even in 0.16. It seems rather to be a combination of Qt and graphics card driver. Perhaps there was a change in the Qt version at the same time with the conda packaging.

I also think that it is Qt related. As I said in my own compiled version using Qt 5.13 the problem did not occur. Or it is related to the OpenGL version used during the conda build vs. the OpenGL libraries installed in OSX, i.e. it could be related to the OSX version. I'm still on High Sierra. Do you know, which OSX version the conda build machine is running on? Which OSX version are you using? Does your FreeCAD installation also suffer from the transparency problem?

Yes (but not the real cause IMO). Qt version has an impact for sure. Apple so strongly want to push their own (probably proprietary) rendering solution that they declared openGL as being deprecated ( ). So the MacOS support for openGL very probably lack some efforts. Guys at Qt made a big effort in Qt5.12 (and probably continuing in Qt5.13) to have all this working fine (for example, Intel GPUs also had problems with the Qt5 openGL).

[tom]

I played with the asm3 branch of FreeCAD and wondered why the transparency problem did not occur there. However, sometimes also the official FreeCAD version does not suffer from the problem. Now I found out why: If I open my project using the menu "File | Open ..." then I see the transparent problem. But if I open the same project using "File | Recent files" then all is fine. Further I noticed an extra error message on the console when opening the project using "File | Open ...":

objc[9173]: Class FIFinderSyncExtensionHost is implemented in both /System/Library/PrivateFrameworks/FinderKit.framework/Versions/A/FinderKit (0x7fffb2f4acd0) and /System/Library/PrivateFrameworks/FileProvider.framework/OverrideBundles/FinderSyncCollaborationFileProviderOverride.bundle/Contents/MacOS/FinderSyncCollaborationFileProviderOverride (0x124daacd8). One of the two will be used. Which one is undefined.

At first it doesn't seem to be related to the transparency issue. But maybe this error message comes from an exception, which prevents the graphics initialisation being completed.

I can confirm the message on opening a file. The message comes, after confirming a selected file, it occurs when opening via menu or icon.
It does not occur on cancelling. It occurs only once, i.e. it is not shown when opening another file.
