System Information
Operating system: Windows-10-10.0.22631-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 4080/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 537.58

Blender Version
Broken: version: 4.0.0 Beta, branch: blender-v4.0-release, commit date: 2023-11-01 18:27, hash: 0b81a163e256
Worked: version 3.6.5

As per the suggestions in a previous bug report I've filed #113352, it was suggested to adjust the default text size in the properties to something like 11.6 on an 1920x1080 monitor resolution set at 100% in the windows display settings:

There is a major difference between the way that the text looks, if changing the default from less than 1.15 scaling to being greater than.

Here are the interface settings with Scale set to 1.15:

And here is how it looks with the interface settings Scale set to 1.16:

Same test on another HD monitor that is smaller and windows resolution is set to 125%:

Same test on a 4k monitor, with windows resolution set to 150%:

Sanity check on first HD montior in v 3.6.5:

At this stage, I am not sure whether it may be some kind of setting with my monitor that is causing the inconsistent font rendering on one of the monitors on which I am testing (the first one). As mentioned in the previous bug report, I have not expereinced these kinds of font rendering inconsitencies with other software, or with the previous Blender version, leading me to belive that there may be some issue in the way the new font is handled.

Thanks for the report, @Dimitar.

In order for me to confirm the report, I need to replicate the issue.
But even reading report #113352, it's still not clear to me what I should look for.

The other report is about character spacing. This one seems to be more about difference in scale.

The difference between the images is very subtle. And the difference in resolution and possible window sizes can be confusing.

@Harley, are you familiar with the issue mentioned here?

I’d probably need more description about what exactly is considered “inconsistent” here, rather than just screen captures.

But if I had to guess I’d say you are seeing some jumps in the text size as you increase the size above some thresholds, rather than completely linear size increases? Or perhaps you are seeing that at some sizes some horizontal mid-height strokes might be aligned at one place and at another size it might be in the middle.

Both of what I have described is normal and expected when Hinting is set to Auto, which now selects Slight hinting. With Slight hinting, horizontal features of the glyphs are altered vertically to better align with the pixel grid. This generally reduces blurriness at the top and bottom of characters. But this will also mean that as you increase the size you won’t get subpixel text heights, but it will stay at 8 pixels high for a while then jump to 9 for a while, etc. And a horizontal stroke in the very middle will be there when the text is an odd number of pixels high, but will be a pixel higher or lower when there are an even number of vertical pixels.

Best is to find a combination that you prefer of font, scale, text sizes, Hinting, and subpixel-antialiasing.
