Ok, please try the new build I sent you then! It had a change made to fix ordering, so I'm hoping that does it. The change is that in "STMultra.cginc" there's a line like this:
#if UI_MODE zed -= 1000; #endif
...And honestly, from some quick edits, I think I'll change that to 999999 in the next release, seems to give an even more consistent result in all canvas modes.
So does it give the results you want in the version with that code? What if the value is changed to 999999? Hoping to publish these updates soon if it all looks good! (There were lots of ultra shader changes made for v1.14.0, so still fixing up some of the loose ends like this... sorry for the trouble!)
