Troubleshooting LaTeX Codes with Fraction Line Disappearance

[mech-eng]

I cannot determine what the problem is. My latex codes have strange behaviors. This might be related to my PC. Fraction lines are disappearing.

What is the problem?

When I put reply button then preview it it looks good.

Thank you.

Have you tried zooming into see if it’s really not there?

It is related to your PC/browser settings. It appears just fine in my browser.

What could I do to fix the problem?

I think @Greg Bernhardt can help. There were similar problems before associated with a browser setting associated with some kind of rapid rendering. Greg may remember what setting it was.

Meanwhile, please post what browser and browser version number you are using.

Chrome. It reads it is updated. There is a number: 73.0.3683.86 and a writing something as "formal compilation".

How about the font size setting? It may affect the rendering too.

How about the font size setting?

This is what @Greg Bernhardt's reply was when I asked a similar question.

I would use the zoom feature rather than mess with specific font sizes.

I mentioned zooming in earlier (see post #2) but apparently it got lost in the stream of other posts.

Sometimes graphical rendering will lose a horizontal or vertical line of one pixel width if positioned at a fold where everything along the fold is skipped to keep the aspect ratio intact. Zooming in helps you to see if that's the problem or not and font size adjustments can help make this disappear.

Yes, when zooming in, it works. Thanks. I could never have thougth zooming could cause such a problem.

Its not the zooming but the notion of how aspect ratio is kept. There is only so much horizontal and vertical resolution available and so invariably a row or column of pixels is sacrificed in the interest of preserving the aspects of the image being rendered.
