Discussion Overview

The discussion revolves around troubleshooting issues with LaTeX code where fraction lines are reportedly disappearing. Participants explore potential causes related to browser settings, font size, and rendering issues, with a focus on the visual output of LaTeX in different environments.

Discussion Character

  • Technical explanation, Debate/contested

Main Points Raised

  • One participant reports that fraction lines are disappearing in their LaTeX code and questions the underlying issue.
  • Another participant suggests zooming in to check if the fraction lines are actually present but not visible.
  • Some participants propose that the issue may be related to the user's PC or browser settings, noting that the output appears fine in their own browsers.
  • A participant mentions a previous similar issue that was linked to a browser setting and suggests contacting a specific user for assistance.
  • There is a discussion about the impact of font size settings on rendering, with suggestions to use zoom instead of adjusting font sizes.
  • One participant explains that graphical rendering can lose lines of one pixel width due to aspect ratio preservation, which may be the cause of the issue.
  • Another participant confirms that zooming in resolves the issue, expressing surprise at the impact of zooming on the rendering.
  • A later reply emphasizes that the problem is not solely due to zooming but rather how aspect ratio is maintained during rendering, leading to potential loss of pixel rows or columns.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the exact cause of the disappearing fraction lines, with multiple competing views on whether the issue is related to browser settings, zoom levels, or rendering mechanics.

Contextual Notes

Some assumptions about browser settings and rendering behavior are not fully explored, and there is an unresolved discussion on the specific browser version and its impact on the issue.

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.

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.
