As one of Vuo's developers, I work on Vuo's engine (the thing that makes compositions run), work on nodes, and write documentation. You'll see me on the forums answering people's questions about Vuo.
I enjoy using Vuo to make live music visuals. My hope for Vuo is that it will grow into a community of people of diverse backgrounds and identities making lots of different artistic, useful, unique, goofy, beautiful, crafty, wonderful compositions.

kokot, that is really weird. Thanks for making the video to help explain it.
Based on the appearance of the glitches — the fact that they cover only certain areas of the editor, and the fact that they're gray rather than another color — it looks like an issue with the Vuo editor's GUI system. (Probably unrelated to those glitches in running compositions.)
The Vuo editor's GUI is based on the Qt framework. We periodically update the version of Qt that Vuo uses. It's possible that the glitches are caused by a bug in Qt that will be fixed in a future update.
Since you marked this bug as low severity — and, to be honest, I'm not sure how our team would go about debugging the problem since we haven't seen it on any of our test computers — I think we'll check back with you after the next time we update Qt (sometime after the 2.0.0 release) and see if that fixes the problem.
iaian7 — I'm finally coming back to this… I set up a test on my computer (attached). Using Vuo 2.0.0-beta3, I ran the composition in fullscreen and as a screensaver for a couple minutes each. Not counting the first moments while the composition is getting started, I saw 0 frame drops in fullscreen and 2 in screensaver (a small enough difference that it might just be due to chance; unclear).
Have you learned anything further in your own investigations? Would it be possible for you to post your shader? And, as Magneson suggested, could you post the system specs (macOS version and graphics card)?
