In the attached repro file, I have a frame containing a UIListLayout, a ScrollingFrame, and a TextButton. It’s fine when it’s initially created, but as soon as anything the UIListLayout is looking at is updated (frame visibility, another element added, child name changed, etc) the button disappears. If I position the parent frame at Y=(1,-(sizeY+5)) or further down the screen the button remains visible, but as soon as the frame is moved to Y=(1,-(sizeY+6)) or further up, the button becomes visible. This may be an issue with off-screen clipping calculations.

This happens 100% of the time and is reliably reproducible with the steps mentioned above if the GUI is tweaked in Play Solo.
