[Solved] Canvas zooming in and out when selecting elements or mouseover on the Inspector

Unity Engine
1

Hi all, I have a bizarre situation where I’ve made a Canvas with some elements on it. In seemingly random ways, when I select elements (just a single-click) in the Hierarchy, sometimes the Canvas zooms in a ways. Other times it doesn’t. Also the Canvas will zoom in and out a certain distance when I simply mouse over the Inspector (no clicking), which makes zero sense because it does it with some objects but not others. I’ve tried viewing in 2D, 3D, both types of cameras, and it’s still happening. The real issue is that the zooming makes it more or less impossible to see where elements will be in the finished game (how large, whether they are off screen or not, etc), because the “bounds” rectangle doesn’t change to match. In Game view it doesn’t happen as much, but still does sometimes. Very strange and can’t seem to figure out the pattern.

If it’s a feature, that’s fine, just want to know how it works and if there’s a way to turn it off…

Thanks!

OK, never mind. I changed the Canvas Scaler to “Constant Pixel Size” and that fixed it, so I can use that while developing. It still doesn’t explain the behavior when it was on “Scale to Screen Size”, because I wasn’t changing the screen at all, just selecting different Canvas elements and/or mousing over the Inspector (?!), and it was definitely inconsistent through a lot of testing. Anyway, all good for now, but that weird behavior might need a look. Thanks.
