Any recent updates to OpenGL?

I do engineering work in VariCAD. It offers three display options per object: "Shaded", "Transparent", and "Wireframe".

This has worked extremely well until recently. Now, when I start the program, I get an error stating that it cannot "initialize OpenGL extensions" and that it's reverting to "OpenGL 1.1".

I contacted their tech support and at the same time uninstalled and re-installed successively older versions, thinking this to be a VariCAD problem. Now that I'm seeing the same behavior on older versions of VariCAD, and given this problem only recently started happening, I'm beginning to wonder if it's something in the guts/kernel of Ubuntu that got updated and broke the ability to start OpenGL.

Upshot is, we have no "Transparent" capabilities now, which worked fine before.

I would suggest to upgrade the driver.

Run in a terminal

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo apt install nvidia-driver-418
sudo apt upgrade

Most likely this will fix the issue on the 5.3 kernel.
