UI [Case 744954]ContentSizeFitter clipped custom fonts incorrectly in 5.3.0f1

1. What happened
Using UI Scroll View with the content controlled by Vertical Layout Group and Content Size Fitter with some font will clipped the last line incorrectly. In 5.2 it displays correctly.

2. How we can reproduce it using the example you attached
Go to Scenes folder in Project tab.
Load Test Scene 1.unity
Go to Dialgue UI Canvas/Subtitle Scroll View/Viewport/Content/Text
If turn on ContentSizeFitter, the text child GO will got clipped and the 2nd line will not shown.
If turn off ContentSizeFitter and adjust the Text child gameObject, the text will display correctly (2 lines)

The built-in Arial font works as expect, but Courier Prime Sans that I use won't. A workaround is to set vertical text to allow overflow.

 

I sent the font that have issue and give more detail steps to reproduce in Case 746238.

Courier Prime font family works with 5.2 fine. I test with open-source Liberation font family, that ones work fine. I think there is a height checking issue with Unity UI in 5.3

 

Thanks

 

Hi I tested with 5.3.0f2 that was released earlier today, and the problem is still exist.

 

Noticed the same thing happens with text in a Layout Element within a vertical layout group. A single line of text will be clipped so that no text appears at all.

 

Confirm - Unity 5.3.0f2 has issue with custom font clipping.

Here is example:
Button has HorizontalLayoutGroup & LayoutElement on it
Text Layout properties says that Height/Weight affected by Text, but still it's rectTransform is rezised to "Fit" text, and it's clipped.

If I change font size it's rectTransform height changes as well, but why?
and at some point when Font size is 33 - rectTransform height becomes the same as the Button rectTransform height, and it's strange.

Here is some screenshots:

 

I feel I should add that most of my game's UI is scrollboxes with Vertical Layout groups containing auto-sized text rows as LayoutElements, which means that in Unity 5.3.0f2 pretty much all of my text has disappeared. So please fix this before actual release, because I'm pretty sure there are a lot of people who have similar UI's that will be quite confused when all of it disappears.

 

You can set the texts to allow overflow as a workaround in the mean while.

 

True, but I was relying on it being truncated when the text actually was several lines long, so it doesn't really work in my case.

 

we are facing the same issue with contentsizefilter in 5.3.0f2. Hope next release will fix this issue~~
