What's wrong with font rendering?

What is wrong with UI fonts on this OS? I don't know if anyone else has the same problem, or if this is maybe an NVIDIA drivers problem. This is not new; the font is blurry. Then, I must go into scale and set it to 150%, then back to 100%, and the fonts look normal. However, after some time, it reverts back.

If the default Segoe UI font, doesn't work for you, you can change it.

But It's not a problem with font itself, when i switch scale to 150% and back it to 100% looks OK, like that something reset display, I don't know how to explain. And BTW this is new windows installation only drivers and Firefox installed.

I had to do it when I had a tiny font size too small to be readable showed up in Firefox. Had to reset the Windows display scale to correct the issue.

Might look in Settings, Personalization, Fonts. I got there by putting Clear Type in the Search box.

what Berton says;
Use the Windows + I shortcut to open Settings - Personalization - Fonts

• Click on "Adjust ClearType text" in "Related Settings" to turn it on.
• Check "Enable ClearType" - Click "Next" and follow the "ClearType Text Tuner" wizard.

Clear Type can't do anything about this problem.

I had a similar issue . My fonts seemed grainy and pixelated in light mode but just fine in dark mode. It took some tweaking but here's what I did to get something I could live with.
Since one setting can affect another, I did it in this order.
1. updated video driver. . Mine was Intel so I used Intel Driver and Support Assist to get latest one. It was much more recent than what was on OEM site.

2. set resolution to "recommended" and scale to 100% (you should do your troubleshooting at default settings).

3. Performance Options>Visual Effects>choose "Let Windows choose what's best for my computer.' Restart laptop.

4.. use Cleartype

5. Change to a more readable system font. The default is segoe ui, a sans serif font. For readability, it is recommended you use a sans serif font and there are many other sans serif fonts available that may appear more clear to you than segoe ui. What I did was type out several different fonts in a word document to see the subtle differences and compare them all until I chose what looked best to me.

Note you might have to run cleartype again if you change font.

If any/all of that improves appearance, then you can adjust scale. Not recommended to go over 125% on a laptop. Leave resolution at 'recommended' setting.

You might want to take a look at this neat little tool that changes font size for different aspects of a window. (The icon font not only changes text on your desktop but in file explorer which makes a huge difference.) Driver updates sometimes make it necessary to run this tool again .

If none of it works for you use dark mode

I installed Googles' Roboto font and made it my system font. Nothing I found is crisper and cleaner. Post #3 here System Font

Hi, I am having the same exact issue.

After a clean install, my windows system fonts no longer render properly.

Just like you, sometimes it will look good and change right in front of my eyes.

I can't stand how low quality / jagged the font is now.

Cleartype settings do not help as the problem exists no matter what.

Reinstalled graphics drivers, monitor drivers, you name it.

Really can't figure out what the issue is!

With latest Windows update and NVIDIA Studio Driver 561.09 all is looks perfectly fine for me now.

@TikiMan11 Is it all software that's unclear or just some apps or some dialogs? If the latter, it's dpi virtualization.

I notice the wonky text throughout the entire system, especially in the start menus or dialog boxes. Web browsers are also affected.

Sometimes it looks perfectly fine and then will render right in front of my eyes to something thin and jagged looking.

In games it is less noticeable, but the text still looks off.

Not sure if I have been looking too hard at my screen the past month or so but I swear the text is also a bit jumpy or 3D looking, maybe jittery is the correct term.

I did just replace my degraded 13900k with a 14900k and the issue is still there.

Also I have clean installed twice so far. Whether coincidence or not, I started to notice this issue after one of the Windows updates from Jan. or July.

Sounds like a driver issue like @forumwt had. But if you've already updated your drivers, I'm not sure what else you can do. Hopefully other members will have some ideas. If it were me, I'd test with another GPU (i.e. an old one lying around) just as a sanity check (assuming we're talking about a desktop here).

Yea, testing a new GPU is next on my list.

Currently my 4090 is showing no performance issues or anything odd, which led me to believe it was Windows related.

I will update if there is any news , thankyou!

I ended up turning XMP off and the font issue went away after restarting.

It has not returned yet, which leads me to believe that XMP was causing the font rendering issues.

With XMP enabled, I also noticed fonts and icons looked a bit jittery, as if they were moving. I am guessing this could mean my RAM was unstable or even faulty?

I am considering making a new post so people can give some insight concerning RAM issues, as I am not too familiar with timings etc.
