Visor Primary Display showing grey screen.

[julesvirallinen]

Hi!

I'm trying to follow the tutorial to get started, but I'm getting stuck at the very basics. When I open the Sketch screen, it shows as light grey screen, and does not react to what's happening in the code. However, if I close the screen or press escape, I see a glimpse of what should be there, for maybe 0.5-1s.

I'm running the macOs version.

Any suggestions for how to debug this?

The console output from the dev console:

I also tried this JDK version https://github.com/Visor-Live/visor-builds/issues/6#issuecomment-619467216

Hi @julesvirallinen, thanks for your report. I believe this stems from an issue with Processing and macOS Big Sur. Are you on Big Sur?

If so, putting frame_rate in your sketch should fix the screen. E.g:

frame_rate(60) # Set the frame rate, fixing the issue?

def draw
  # ...
end

Let me know if this works for you!

Hey amazing, thanks so much! Closing the issue. Maybe worth documenting at some point?

[EmperorJack]

Glad that worked out! Good idea, I'll keep that in mind. Upgrading Visor to use Processing 4 (just reached beta 🎉) will likely solve this in the long term, I'll see what I get to first.
