<div dir="ltr"><div>I don't see anything unusual in your output. You have chosen to use \left--\right (it is often better to choose a specific size such as \bigl..\bigr) but if you use \left..\right then the size of the brackets depends on the size of the contained expression and \frac{1}{a} is taller than \frac{a}{1}</div><div><br></div><div>Incidentally avoid using `eqnarray` it is better to use the alignments from the amsmath package.<br></div><div><br></div><div>David<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, 1 Mar 2020 at 16:32, Michael J.

<br>
I've posted this to the math-font-discuss list earlier, but nobody<br>
seems to be there or willing to help.<br>
<br>
Although I have a lot of experience writing .tex files, I have no<br>
experience with the tex-live source codes. Hope I'm at the right<br>
address.<br>
<br>
The attachment shows that the rendering of the brackets in the<br>
different formulas is not very consistent. In my opinion, somebody<br>
ought to have a look at the rendering engine. <br>
