Is this a new 32C Channel AVA plugin?

Thanks, but this does not help.

This is what I do now (having an integrated Intel GPU in the CPU): -I prepend this before the command that starts Mixbus:

  env vblank_mode=0  env MESA_GL_VERSION_OVERRIDE=3.2 /path/to/the/DAW

So now, the plugin's GUIs are fast and snappy, but the plugin's RTAs does still not work. I see no difference if MESA_GL_VERSION_OVERRIDE is set to 3.2 or 4.5. I choose 3.2 because it seems to be the minimum requirement.
