When I run the `paraview` binary supplied via `sudo apt install paraview`, I get the following backtrace:

I’m running Pop OS 22.04 LTS with a Quadro RTX 6000/8000 graphics card. I’d much appreciate any suggestions for moving forward. Paraview is a pretty critical part of my workflow 🙂 I’m happy to provide more details that might be useful. I also get a similar stack trace using the paraview website provided binary

Hi @lindad ,
Please try using our binary package from [paraview.org/download](http://paraview.org/download)
Best,

Hi @mwestphal , I get the same kind of stack trace with the binary. It’s shown at the end of my post above

What is the output of `glxinfo` ?

Let me know if you need to see the GLX visuals or extensions. There is a character limit and I’m not sure how to attach files

Ok this morning I was able to open the apt installed paraview with an exodus file without any issue. What has changed in the last day I think is that I installed qt5 libraries for another project. Either those or its dependencies may have done the trick?

Qt5 is definitely a dependency but it should have been installed automatically.

You’re right, I see it in `apt-cache depends`. So all I can do at this point is shrug and be happy it works. Thanks for your support!
