Opacity mapping makes colors disappear

ParaView Support
1

Simple 2d slice surface view, when using “Enable opacity mapping for surfaces”, the colors disappear altogether.

I feel it might be a graphic card issue. Any ideas on how to debug this?
Thank you for any suggestions.

  • Version of ParaView: 5.7.0
  • Your OS: Ubuntu 20.04
  • Your GPU: Nvidia GM108M [GeForce MX130] (and integrated Intel UHD 620)
  • Your graphic driver: 455.38 (see attached figure)

Upgrade to ParaView 5.8.1 or 5.9.0 (once it is out)

Unfortunately, I could not get the downloaded 5.7.0, 5.8.1, and 5.9.0 rc3 to run;

I missed an earlier error. The full error is below. Looks like I need to specify some paths or flag to allow the downloaded version ParaView to use GL correctly.

Try upgrading your drivers, looks like the last one for your GPU are 460.32.03.
