Mouse click doesn't work at top of screen

Steps causing the bug to occur

  1. Create a full screen window
  2. Move the mouse to the very top
  3. Click … doesn’t work, no single click event received with the “Receive mouse clicks” node.
    Sample minimal composition that exhibits the behaviour.

Have you found a workaround?

Desperately need a workaround, exhibition opens in a few days.

Other notes

  • Vuo version: 2.2.1
  • macOS version: macOS 11
  • CPU: x86_64
  • How severely does this bug affect you? It prevents me from completing a specific task with Vuo.

Panic over. Works if the Window is connected up to the Receive Mouse clicks node.
But still interested in why this occurs. Still seems like a bug.

In order to reproduce the issue, we needed to turn off System Preferences > Mission Control > Displays have separate Spaces. In that case, if you move the mouse to the very top of the screen and click, the counter on the above composition does not increment. If you move the mouse down just one pixel, then clicking does work.

Ahhh, yes I have “Displays have separate Spaces” disabled since I need to ensure the menu bar and dock never pop up, for an exhibition.
This is the other characteristic of exhibitions, the public will find any bug or chink in the armor. :-)

Fixed in Vuo 2.3.1.
