I first experienced this with FreeCAD_0.18-16146-Linux-Conda_Py3Qt5_glibc2.12-x86_64.AppImage though it also reproduces on FreeCAD_0.18-16131-Linux-Conda_Py3Qt5_glibc2.12-x86_64.AppImage
I have searched the forum for others seeing this issue without finding it, though it's possible I'm just not thinking of the right words to search for.
Here's the file open:
Here's what the gray document window looks like:
- QCTP-TopNut.FCStd is the file in question.
- QCTP-TopNut.pdf is the most recent PDF export of the drawing.
- QCTP-Handle.FCStd is another file created together, saved from the same FreeCAD session, that is not exhibiting this bug for me.
