Question

on my monitor at least, chips or gaps appear in these braces

do they also render incorrectly on your monitor?,

also is there a way to fix this ?

Answer 1

\[\large(\overbrace{\overbrace{\color{orange}a
+\underbrace{\color{cornflowerblue}b)(\color{seagreen}c}_{\text{Inside}}}^{\text{First}}
+\color{brown}d}^{\text{Outside}})
=\overbrace{\color{orange}a\color{seagreen}c}^\text F
+\overbrace{\color{orange}a\color{brown}d}^\text O
+\underbrace{\color{cornflowerblue}b\color{seagreen}c}_\text I
+\underbrace{\color{cornflowerblue}b\color{brown}d}_L\\
\large\qquad\quad\underbrace{\qquad\qquad}_{\text{Last}}\]

Answer 2

yes, i see those too.

Answer 3

I also see those. Even when I'm using LaTeX on my computer I see those things occasionally. However, whenever I print the document, they always disappear.

Answer 4

MathJax has three different rendering engines. You could try one of the others and see if it helps.
