Last update broke fonts

Hello I have two machines (labtop) that runs netrunner rolling. One of them is installed from scratch. After update both machines fonts are broken, displayed tearing, as if they low resolution images displayed high resolution displays. They get thinner and can not be read.

I have never played with fonts. I do not know what happened?

Any help much appreciated.

Did you check the opengl rendering settings?
Plasma seems to be not loading the hardware compositor properly after updates, and defaulting to the software rendering as of late. Several times now I have to go in and reapply my settings, even though they seemed to be set properly in the kcm, over the last couple of months due to artifacts.

I however, have not experienced any font issues on my end.
Is this with issue your having with just the desktop, gtk applications, qt applications, or is it with all applications?
You didn’t happen to delete your ~.config/fontconfig/ folder or the fonts.conf file within that folder, and/or the fonts.conf file in your home directory?

Thank you for the reply.

The problem affected the whole system, kde apps, gtk applications all.
In firefox it is more noticeable. Could you please tell me how to check the opengl settings. The only thing I know, which I have not touched is in System Settings -> Display and Monitor -> Compositor. It was using just default setting in all my two labtops.

After frustration, I installed manjaro to see if the problem is netrunner related, and just after update I saw the problem in manjaro as well. I can not blame netrunner, but what can I do to correct it…

I provide the “inxi -Fxxxz” command output.

Honestly, that’s not helpful when it comes to fonts.
All that shows is your using the intel driver.
It’s won’t show if the kwin_x11 compositor is using hardware (Opengl X.x), software (Xrender), or offloaded back to 2d.
That also can’t tell us if the font systems (freetype2), or it’s settings (fontconfig), are working properly or not.

Could you post a screen shot, and/or the contents of your fonts.conf files, etc.

Hello thank you for the reply. I have received help from manjaro forum for the manjaro system. The solution is relavant for netrunner as well. I tried it and solved the same problem of netrunner installed labtop. The discussion is at following link below. Basically it is because of KDE font bug relavant to anti aliasing.

Solution of font tearing problem

Thanks for the link.
I still haven’t seen the issue, but then again I hardly ever reboot.

PS. I also always change my hinting setting to full, as slight seems a bit blurry to me. :wink:
