Do you have another child mask that disabled? – Feller

No. I add mask only on parent that has ScrollRect component attached. – Sellers

Try Bijan's solution. If that does not work, got to Help->Report a Bug... then file a bug report. This question has been asked more than 2x within the last 2 weeks so I believe this is a bug. – Feller

Thanks for your suggestion. – Sellers

Answer 1

I got around this issue by using RectMask2D Component instead of the regular Mask.

Answer 2

If somebody else got this problem and Bahman_Aries solution is not enough, try this:

File > Build Settings > Player Settings>XR Settings (or Other settings if you are working in older versions of unity) > Daydream (click on the small arrow) > Depth Format.

And set that to 24-bit depth | 8-bit stencil.

This is cause you need a stencil buffer.

Answer 3

ScrollRect component has this weird behaviour when an image in its content has its material set to something other than none.

Unset the material to None and it should work.

If every child of content already has no material, then it could be a bug.

There is no material attched to its image content. – Sellers

@vishal you mean those white rectangles has no material? – Selfrestraint

No. I make image content source to None and fill with white color. – Sellers

@vishal no? I added a photo, this is what I mean. – Selfrestraint
