[Bug]: Some VST plugins are launched in white screen

[molarro]

Describe the bug

Some VST standalone plugins, e.g. Serum and Vital after installation are launched in white screen, however I can hear sounds. In DAW, plugins are loaded also without GUI.

I have tried with Nvidia proprietary driver, so as with Nouveau.

If I launch .exe via terminal, I'm receiving (I don't know how to copy):

So, I think one of the problem was - Vulcan has not been installed. After installation in terminal:

Failed to create surface

I guess it is well known issue:

Maybe "Bottle" has already any solution?
