Blurry output example

SUMMARY
Markdown output with LaTeX code, or LaTeX entries look blurry under fractional
scaling (for instance 125%).

STEPS TO REPRODUCE
1. I am for instance introducing the following code in a Markdown/LaTeX cell
in, for instance, an Octave Cantor instance (I run into the same trouble
anywhere else):
---------------------------------------
We want to solve a PDE of the form

$$ \left\{\begin{array}{ll}
     u_{x x} + u_{y y} = f (x, y), & (x, y) \in \Omega\\
     u = 0, & (x, y) \in \partial \Omega
   \end{array}\right. $$

for $\Omega = (0, 1)$ and $f (x, y) = 2 \pi^2 \sin (\pi x) \sin (\pi y)$. We
know the exact solution to be

$$ u (x, y) = \sin (\pi x) \sin (\pi y) . $$
---------------------------------------

2.  Execute the cell

OBSERVED RESULT
The output is fine, except for the LaTeX interpreted entries, which look
blurry.

EXPECTED RESULT
They should not look blurry.
