Canvas Scaler behavior seems to be different from 5.3.0, im not sure if it is because I was using it wrong and somehow making it work before and now it got fixed, or if it is because it is bugged in this version.
I stopped using it anyways, turns out I didn’t need it, but im curious to know if other people encountered this problem.
I think it had problems updating itself (camera zoom was changing but scaler kept same size all the time) when I was messing with it.
What is the exact difference, as this could be related to my UI issue, just couldnt explain it properly…
Are you two on Mac with retina screens? Note that on Mac with retina screens the Game View is now in retina resolution (because the entire editor is) so every pixel is half as big. Depending what settings you use for CanvasScaler, that might affect how things look. Just a guess.
How a change in Unity 5.3.0 related to beta though?
I am not on Mac, and im saying the canvas scalers worked fine in 5.3.0, but when I upgraded to beta they broke/changed somehow.
Something is changed about Canvas Scaler for me also.
It seems that it’s not “triggered” on first start to render canvas according to Camera when render mode of canvas is set to “Screen space - Camera”.
If I then disable/enable canvas gameobject or for example resize Game view that it changes it’s size for at least 1px canvas will be successfully rerendered in proper size.
Edit: I forgot to mention that I have just downloaded and tried beta 5.5.0b3.
Yes this is the problem I seem to be having also, thank you for the detailed explanation to the Unity Team.
I can confirm this is the case. I’m using 5.5.0b3 but I think I experienced this behaviour in b1 as well.
I have a Canvas in Screen Space - Camera. When I “zoom” the camera by changing its orthographic size, the HUD elements do not scale. If I make any change in the Canvas Scaler component everything seems to snap back to the correct place.
I was also able to reproduce it on an empty project with only a camera and a Screen Space - Camera Canvas with a Text element inside anchored to the top left corner, and changing the camera’s orthographic size.
To work around this issue for now I’m changing the referenceResolution property of the Canvas Scaler via script by minuscule amounts to force an update.
If you were able to create a repro project did you create a bug report for Unity team to take a look at it.
Yes I’ve just sent it.
Small update: Setting canvas to “Screen Space - Overlay” has fixed issue for canvases. They are rendered “fullscreen” taking whole area of camera view. But I didn’t plan to use them like that so it’s not rendering parts of my game as I have planned.
@andrecosta : Is there some link to reported bug issue? I would like to track to see if there will be any progress with this.
The issue ID is 831304.
Maybe I can find another workaround to do what I need without relying on zooming the UI’s camera since this was my main issue. I’ll keep working on it in the meantime.
Hi everybody,
The UI team has been notified about this thread.
Any news on this, really need a fix in next beta or cannot make release of game.
I’ll have to take a closer look tomorrow when i get some time. Though dont have any news on why its happening or any work around.
This is the link to the issue on the public issue tracker. Unity Issue Tracker - UI objects don't snap properly when changing camera orthographic size/game window size until Canvas Scaler is toggled twice. I voted for it because it’s a ship blocking issue for my game as well.
Any news on this beta 5 has no changes?
@phil-Unity : Can you give us some update regarding this? Did you guys at the Unity been able to reproduce the issue? There is same problem about Canvas Scaler in another thread also : Screen Space - Camera Canvas and Orthographic Camera - Unity Engine - Unity Discussions
Looking at the
it says : Status: Fixed in Unity 5.5.0. But I’ve just tried out 5.5.0B8 and for me the bug still remains.
Then how does it say that it’s fixed? In what version of 5.5.0?
This issue still exist and broke my whole game as it was based on UI. 
We cannot release games unless this is fixed, should it not be top priority!! wtf
