Report Word Wrap in Wrong Position and Display Differently on Different Machine

[yeetobiichi]

Hi,

Our company has updated to latest JS version now (2025.3.4). We've noticed that some report still might display differently on different zoom scale. Specifically for this report, when displaying on 100% zoom, the word wrap calculation doesn't apply correctly.

My current speculation is that, when using the "SimSun" font, together with Chinese Character/English/Number, the width calculation has some error, causing it to not break line properly.

Another related bug is that, when setting the "Allow HTML Tags" property on for that specific Table Cell, it might just truncate my data, cause it to be invisible.

Attached are the images and the original mrt File.

Browser: Edge, Chrome (latest version)
Systems: Windows 11 (latest version)

Thank you.

Hello,

> ... some report still might display differently on different zoom scale.

We found a bug in HTML export: font sizes were being rounded to integer values.
Therefore, if the scale was not 100% or the font size was initially fractional, it was truncated to an integer value in the HTML.
As a result, the text appeared smaller than expected, and line breaks occurred in the wrong places.
The issue has been fixed and will be included in release 2025.4.2.

This is not a bug in our product, but a known behavior of text rendering in Windows systems.
In Windows, the text rendering methods round internal font metrics to whole pixels.
As a result, when font sizes increase smoothly, the actual rendered text size grows in small jumps rather than continuously.
That means in some cases the text should be slightly smaller for the given font size, but the system renders it larger, causing it not to fit within the cell.

In this report, the text box has a font size of 11pt, and with a 75% scale, the effective size becomes 8.25pt.
If you manually set the font size in HTML to 8.24pt (just 0.01 smaller), the rendered text size decreases and fits into the cell correctly.

Similarly, if you change the browser page zoom (without changing the viewer’s scale), the problem also disappears.

Possible workaround:
Set the font size to a slightly smaller value, for example 10.95pt instead of 11pt.

Thank you.
