Hi, Maybe I'm misunderstanding something simple here, but I just upgraded to Unity 5.2 this morning and I'm now having several issues with many of my UI buttons. After troubleshooting for about 3 hours I discovered that some of my buttons fail because the touch seems to interact with objects beneath the layer my button is on. This was previously never a problem. In the screenshot below, there are areas of the Yes and No buttons that don't respond because it seems the click / touch interacts with objects beneath the popup menu. In this example, I have a Confirm screen with a semi transparent disabler background that previously prevented interaction with the objects below. Now with 5.2 it seems that in some odd cases a touch can interact with objects below the disabler.. weird. I'm going to continue experimenting to provide more clarity here, but if anyone knows something simple that changed in 5.2 that would cause this issue please let me know.
