Hi,

I first installed ParaView 5.10 on my Linux machine (Ubuntu 22.04.5 LTS), but the simulation results (OpenFOAM) are only displayed in a small square frame on the left corner, and the rest is a default gray background. The size of that square frame is very small, not because the camera is zoomed out but it’s like the rest of the simulation has been “covered” by the background layer.

I did the installation according to the website ([Download v12 | Ubuntu](https://openfoam.org/download/12-ubuntu/)). What is the problem and how can I fix it?

Many thanks in advance.

This is OpenFOAM website which suggest to use the ParaView debian package.  
Neither the OpenFOAM website nor the ParaView debian package are maintained by Kitware.

This is a graphic driver issue / mesa issue. Use the binary package of ParaView: [https://paraview.org/download](https://paraview.org/download) or fix your driver issue 🙂
