TechDraw printouts - almost invisible projections

What does about show for the Debian install that works?

Qt 5.15.2 using X. I was thinking the issue might be 5.15.2 + Wayland until your report of problems with X11.

Would it be worth creating a very simple TechDraw document and seeing if there are any differences between ones that work and that don't?

Doesn't seem to involve the complexity of the document. Yesterday I set up Ubuntu 20 in a VM (gnome, Qt 5.15.2, wayland). Using a simple drawing of a Part Cube and Sphere, FC didn't display vertices, didn't change line widths and had extra lines in the drawing.

This is how it looks in FreeCAD itself

First time I've seen Qt 5.15.3 in About FreeCAD. Guess I'm back to blaming 5.15.2.

If anyone else is interested in testing Qt5.15.3 --> I'm using the unofficial snap edge (thanks to @ppd)

I have Qt 5.15.2 on Debian, and printing and TD in general works well. However, Debian often heavily patches their stuff, so the Debian version of Qt 5.15.2 may contain some Debian-specific fixes and patches. Some of the Qt libraries on my machine appear to be "5.15.2+dfsg-16", which mean there are sixteen consecutive Debian-specific releases, each containing patches for whatever changes, added on top of upstream 5.15.2. Most of these Debian patches are supposedly minor, but who knows..? So, if Qt 5.15.2 works for Debian, it might not be a very good indication of the upstream Qt 5.15.2 working in all cases.

Think we can rule that out as compiling it myself from git works.

You have compiled the Qt libraries from the git sources? I've heard that is enormously difficult and slow, so kudos there!

But yes, my situation is Debian-sid distributed libraries for everything (Qt 5.15.2 included), and self-compiled FreeCAD based on these Debian-distributed libs. Everything works here, too.

I'm wondering that if it's not Qt 5.15.2 that causes the problem for some people, could it be Mesa? Debian still has Mesa 21 for OpenGL 2D and 3D, but Mesa 22 has been recently released. But that is just guessing...

Sorry, I meant that I had compiled FreeCAD from git and Qt 5.15.2 from Ubuntu 21.10 repositories which should have come from Debian - the highest dfsg I can find is 12. So maybe a few patches below what you are using?
