Hi, I’m new to ParaView and I’m following the tutorials given in the [textbook](https://www.paraview.org/Wiki/images/b/bc/ParaViewTutorial56.pdf) provided on the website.
I’m using Ubuntu Mate 20.4 and my version of Paraview is 5.9 (the latest, I think).
Following Exercise 2.14 (plot over a line in space) I get a weird GUI problem: the line plotted looks discontinuous and trembles when I place my mouse on it.
I attached a video below.
Do you know if there is a way to fix this problem? Thank you in advance

This looks like some kind of driver issue.
Could you paste the content of the Help → About dialog ?

Yes.
nouveau should work but is not highly tested. Could you try with nvidia or mesa instead ?

Unfortunatley I don’t know how to do it. May I ask you what OpenGL Vendor means? And how can I change it to Nvidia or Mesa?

This is related to your graphic drivers.
On linux mint, installing nvidia proprietary drivers is actually quite easy, see here:

Thank you Mathieu, now it works perfectly.
For those who will be interested in the topic in the future, I briefly report how the problem was fixed (using **Ubuntu Mate 20.04** ):
1. In the upper panel go to System
2. In the System Menu go to Preferences \> Hardware \> Additional Drivers
3. Now, a list of all the available driver should appear. I selected NVIDIA driver metapackage from nvidia-driver-460 (proprietary, tested)
4. Click Apply Changes and on pop up windows always press next.
5. When the installation finishes, restart Ubuntu.
Now everything work as expected.
Thank you again Mathieu for your time and for being so quick.
