InputField caret position changes with font size (4.6.4p3)

Using Unity 4.6.4p3, all my input fields have incorrect caret vertical position now.

The problem seems to be that as the font size of the text component increases the vertical alignment of the caret (and selected text highlighting) gets more and more off center and is pushed off the bottom of the input field.

Is anyone experiencing this same issue? Is this a bug? Any help would be appreciated.

 

Yeah, noticed the same thing in 4.6.4p4. Highlighting text is also misaligned.

 

I reported a bug (693093). This doesn't happen in 5.0.1p2 or 5.1.0b4 though and 4.6 bugs don't seem to be a high priority.

 

Bumping for any new info on this bug. Still an issue in 4.6 versions after 4.6.4p3

 

Same thing happening on 5.1.1f1 (also tried 5.1.1p1, didn't help).

It's especially rough with multiline.

 

Does anyone have a working fix for this? If I could, I'd manually hack in the numbers to align the caret correctly, but it seems that this only works, when called after selection.

I've been trying to set the correct position in OnSelect, but then it only works the second time my field becomes selected. The first time is still ignored. Pretty annoying.

 

The workaround I'm using for now is to fix the alignment like you mention, but I do it each update or lateupdate but also make sure that the script that does it is set to run after all others in the script execution order.

 

I made this fix using a custom formula.

caret.posY = caret.posY + (('Font.Size' - 'Working.Font.Size') * 'Scale.Ratio')

Terms:

Working Font Size: The font number where the caret is always on target.

Scale Ratio: Set value to change caret position relative to the font size.

Arial Default Values: Workning.Font.Size = 14, Scale.Ratio = 0.84

Hope this helps.
