Hi everyone,

I’m having a problem with ParaView when trying to visualize my CFD simulations run with ParaFOAM/OpenFOAM. Only a small portion of the display screen shows the simulation correctly, while the rest remains blank or incomplete. Sometimes the whole display works but with some small display portions that are hidden

. This happens regardless of the simulation complexity — I’ve tested with both simple tutorial cases and more complex projects, but the issue persists.

I’ve already tried updating my GPU drivers to the latest version, but it didn’t solve the problem. Does anyone know what could cause this partial rendering and how to fix it? Any advice or troubleshooting tips would be greatly appreciated!

Thanks in advance.

Looks like driver issue.  
Which OS are you using ?  
Which GPU and GPU driver are you using ?  
How did you install ParaView ?
