Scrollview mouse inputs (Drag/Scrollwheel) on content work inconsistently

Unity Engine
1

Hi,

QA recently found that scrolling content directly by dragging it or mouse-wheeling it does no longer work, though we didn’t change the UI setup.

The situation is:

Scrollrect

Vertical layout group

Window A (input on this one works, its driving the scrollrect)
Horizontal layout group

Vertical layout group A

Window B (not working)
Window C (not working)
Verticatl layout group B
Window D (not working)
etc

Scrollrect itself is stretched to full window size. Layout groups resize based on content.
Both scrollrect and layout groups have no raycasted images on them whatsoever because I need any space between the windows pass occuring inputs through. However, if I add images to the layout groups it starts working.

We are usually always working on the up to date Unity version, so this problem might have been introduced with a new update.

Thanks,
Philipp

Well… I have a workaround! I’m not sure if it worked someday or if I always used my workaround!
