Problem with UI on 2019.3b10+

Unity Engine

Hi!

Is there some change how the UI handle Z posttion on 2019.3b10 and later versions?

UI is not detecting anymore click on some UI Items that have differents Z others than 0.

Am I the only one facing this problem? Until 2019.3b9 all works fine…

I found this on 2019.3b10 release notes. Maybe the problem is related to this changes?

  • UI: Changed the order of checks so the most resource intensive check is perfomed last, and only if needed. (1180358)

  • UI: Comparing the depth of nested Canvases now uses the depth value used for rendering. Depth values that are set but not used are ignored. (1176348)

I think I found the problem!
Disabling “Ignore Reversed Graphics” fixed the problem…

But that is strange because I never changed this.

Hi @wagenheimer ,

Could you please submit a bug report for this issue? There was a calculation change to how it is determined whether an item is facing the camera or not and this sounds like unintended behaviour. There is a known issue that might be the culprit here but it’s not certain that it’s the same problem: Unity Issue Tracker - Canvas UI elements are not interactable when Canvas Screen Space - Camera property Plane distance is less than zero

A fix for that is on it’s way.
