Loading image gives Access violation

[kisolre]

Trying to load an image to use as a reference fails under recent windows Conda builds giving:
Unhandled Base::Exception caught in GUIApplication::notify.
The error message is: Access violation

I was using FreeCAD_0.18.15248_Conda_Py3QT5-WinVS2015_x64 so I downloaded latest FreeCAD_0.18.15316_x64_dev_win, FreeCAD_0.18.15316_x86_dev_win and FreeCAD_0.18.15316_Conda_Py3QT5-WinVS2015_x64 builds and only the Conda one gives that error again. The other two load the image just fine.

The version that the Conda build reports is 0.18.15299 and not 0.18.15316 as the downloaded file which is strange.

edit: So it looks like this might be fixed with Qt 5.12.1 which is used in latest development builds . If you encountered this could you try with FreeCAD_0.19.17477_x64_LP_12.1.2_PY3QT5-WinVS2015.7z build (or any later that 17477) from here https://github.com/FreeCAD/FreeCAD/rele ... g/0.19_pre and report your result?

What procedure are you using to load the image? I tested some options on Linux, using Conda based AppImage. To see if any general issues could be observed.

Didn't detect any issues when loading images from the Image workbench and from the File menu.

Best to ask here:

And to first determine if this is a Windows re-packaging related issue. Or a general Conda environment FreeCAD package issue on Windows.

All machines running Intel HD Graphics are showing this access violation message

GeForce GTXes are offering no problems.

One can reproduce this error simply by switching graphics card, using same machine and same build.

BTW all drivers are up to date

BTW all drivers are up to date

The Radeon issues reported here could be solved downgrading to an older driver version . Perhaps it is here worth a try too.

OK therefore this could be an issue specific to Qt5 builds (maybe some specific Qt5 version) and to some graphic card drivers (Intel on Windows 10). Does the crash always occur if this command is used?

https://www.freecadweb.org/wiki/Image_CreateImagePlane

If yes, could somebody experiencing the crashes test, on what happens if the image is first imported on Qt4 build, and saved to a file. If after that file is opened on a Qt5 build.

(means: yes)

what happens if the image is first imported on Qt4 build, and saved to a file. If after that file is opened on a Qt5 build.

(means: exception is thrown)

[triplus]

Could be an issue related to on how we display images in the 3D View, and some GPU drivers not liking it (Coin3D or driver issue). Does it crash when File -> Open -> Image procedure is used (Qt 5 version or driver issue)? Is anybody prepared to test Conda FreeCAD build directly on such hardware? To rule out re-packaging issue.

Anyway, it likely makes sense to open an issue report on the issue tracker, if more verbose crash info can be provided.
