We need some more sizes of braces. The suggestions in bug 407101 and bug 414277 would resolve this.

Interestingly, the rendering is different on the latest Camino trunk. Only the smallest size under- and over-braces are used.

Created a webpage that shows this bug and how it screws up putting braces inside of table cells (Same as image provided). It looks like the brace's size is not given to the table so that the table can position the braces correctly, there should be a 3px padding. https://eyeasme.com/Joe/MathML/OverBrace_UnderBrace_Bug.html

Bug seem to be fixed as the attachment shows, BUT there seems to be an image degradation as the next attachment/comment shows.

(In reply to comment #8) > Notice that the underbraces are less defined in the latest trunk release. If you are referring to smaller hooks and thinner lines, I think that's just from rendering at small font sizes and from STIX fonts choosing to make the line thickness similar to the thickness of stems in other characters. Fixed after changes in bug 407101.
