Weird plot over line formatting | ParaView 5.9 on Ubuntu 20.04


I have ParaView 5.9 binary installation on Ubuntu 20.04. Strangely, the entire plot over line window uses dotted lines alone, even for text. I have attached a screenshot for reference.

Is this an issue of dependencies? My Ubuntu installation is relatively new. Or is it that 5.9 is not supported on Ubuntu 20.04?

Thanking in anticipation

That is a 8 year old GPU and most likely the culprit. Do you have another GPU on your machine ?

Unfortunately no. So what can I do to fix this? Use a different version? Earlier 5.6 worked on my PC with Ubuntu 16.04. I have now done a new Ubuntu installation.

Yes, we changed Qt things between 5.6 and 5.9, so that may explain it.

You can use mesa instead, by running ./bin/paraview --mesa
