Is this a new 32C Channel AVA plugin?

That's my result for the Graphics:
          Device-1: Intel Xeon E3-1200 v2/3rd Gen Core processor Graphics
          vendor: Hewlett-Packard driver: i915 v: kernel bus ID: 00:02.0 chip ID: 8086:0162
          Display: x11 server: X.Org 1.20.10 driver: intel resolution: 1920x1080~60Hz
          OpenGL: renderer: Mesa DRI Intel HD Graphics 4000 (IVB GT2) v: 4.2 Mesa 20.3.4
          compat-v: 3.0 direct render: Yes

It seems usable, just sometimes the responsiveness of the graphics seems to freeze for a very short time.
Question : is there a way to disable the tooltips ?

Not sure what disabling tooltips would do. I could be wrong, just don't know.
You can disable globally in preferences >  appearance > Show Tooltips... (MB32c7/Ardour 6.8)
maybe some background process intermittently hogging resources?
I know wifi scanning for networks has been known to interfere with audio streaming.
maybe graphics priority issue? not sure how to correct that, just throwing out ideas.
