How can I fix MathJax font formatting looking off?

Things I have tried

All formulas look a bit off as far as formatting goes.
This only happens on my Windows machine (formulas look fine on MacOS)
I have tried making some CSS snippets with ‘letter-spacing’ and ‘word-spacing’ parameters, but that doesn’t seem to solve it.

I’m not sure how this should be approached, and would very much appreciate your help.

What I’m trying to do

I’m trying to change the font and spacing of MathJax formulas. The current font looks very bad, however I’m not sure how it can be changed and what would be a preferable font.

Also, the spacing makes these formulas illegible to me, and none of the CSS properties that I’ve tried seemed to have solved this issue.
