Look at the capital Ms and Ns in the text. The left vertical legs of each is very thin. This happens with other vertical lines as well, but is easily seen in the Ms and Ns. Horizontal lines seem to be affected too to a lesser degree.
Bplus' images show a much more degraded lettering than mine though. The difference between operating systems perhaps?
I had this issue with "thin" letters ages ago, with my new PC. Turned out it was a problem with FXAA anti-aliasing working too hard to smooth images all the time, and that tended to fade out the edges of my letters.
Since this is using a newer version of TrueType, I would guess that it's trying to do this same type anti-aliasing with the letters. Just for curiousity's sake, can you go into Nvidea Control Panel and turn FXAA off and see if the issue persists? (It may require a reboot; I don't remember if it does or doesn't.) If that's all there is, then there may be some option in the new library to toggle that effect off for our letters.

Well that didn't go well! LOL Thank goodness I made a restore point before attempting the driver upgrade. Someone else will need to check their nVidia settings. It seems I have a video card issue to sort out now. Yeah.

Here I show v3.10 print (left) versus v3.12 print (right side).
So was something changed in the way of handling fonts in IDE?
Well, we moved to the current version of FreeType (2.4.12 to 2.13.2). The one that we had before was from 2013.
What / Where is FreeType used? I thought I was using a Windows Font?
I am seeing the shoddiness in allot of the verticals n, m, u, h, d, b, p... Lucon under 18 wasn't so great before this change but 18 really looked great! Really pleasant on these old eyes. Now although 19, 20 improves quality a little, it's just not nearly as good plus I lose too many characters per line and too few lines in screen height to go higher. Need over 100 chars across and over 38 lines down.
What was reason to change? It was just newer? Did this change improve something else like font print quality in output screens?

Wow! I love the _CRC32 and _READFILE$ commands!
Thank you @RhoSigma-QB64 for these nice additions.

@bplus @TerryRitchie I think what you are seeing is the change in the subpixel hinting behavior in newer versions of FreeType. Technically this would mean that any application that uses the current version of FreeType will have the same behavior.
That said, I think there is a way to tell FreeType to select a different hinting behavior with FT_LOAD_TARGET_xxx
https://freetype.org/freetype2/docs/hinting/subpixel-hinting.html
https://freetype.org/freetype2/docs/hinting/text-rendering-general.html
The good part about all this is that _LOADFONT takes optional comma separated parameters:
handle& = _LOADFONT(fontFileName$, size&[, "comma_separated_parameters"][, fontIndex&])
So, we could easily introduce some new options for _LOADFONT that allows us to pick the hinting type we want.
We can perhaps use the older hinting behavior by default and let users use the newer behavior or FreeType default behavior if they want.
Interesting stuff really. I'll deep drive into this when I get some time.

"different hinting behavior" wow sounds like we are training AI ;-))
I guess fonts are no longer written in stone.

Why is it every time I type a line of code, the new IDE has a message box pop open that says, "Steve is laughing!" Aside from that, it's installed, up, and working.
