I have a ScrollRect with a mask set. The contents are dynamically added and consist of a number of headers with a content grid made up of buttons with sprites on them. There are a number of problems I'm running into, which you can see in the attached video: Some items are masked and some are not. The sprites (or the button containers) are jittering, which seems to indicate some resizing/positioning is happening, despite them being children of a fixed size grid layout. I have "preserve aspect" set on the button image, which works, but some sprite images are outside the bounds of the button size set by the grid layout constraints of 62x62 Any help for these issues would be appreciated!
