[SOLVED] Extreme blurry fonts in some applications

Hi dear all,

unfortunately I have some issues with my fonts: In some applications like okular or texstudio the font is rendered extremely blurry:

The system-fonts however seem to be rendered quite normal.

I tried this for my /etc/fonts/local.conf:

Has anybody an idea how to solve this problem?

Kind regards

Solution:
This issue was caused by scaling in KDE -> reset scaling to 1.0 (and set dpi for fonts)

Hello! Does the font renders normally if you try to zoom in the page that contains it?

Any chance you can post the actual pdf output of LaTeX?

Re: [SOLVED] Extreme blurry fonts in some applications

I have the same issue - All pdfs on Okular are blurry, and so are fonts in the texstudio editor. Evince reader does not have this problem.

I am not sure if this is due to a system upgrade today. Here's the relevant output from pacman.log:

Setting display scaling to 1 in KDE system settings and increasing font dpi fixes this issue for me.

Re: [SOLVED] Extreme blurry fonts in some applications

I have some applications that are using some small fonts to start off with...maybe it's the fonts I have installed...but I checked against two machines and tried to make them have the same fonts installed, but nothing different.  Then when I change resolutions with xrandr to higher, the problem doesn't improve.  I've even used xmag at the higher resolution, and it doesn't magnify the fonts to anything readable.  It has been that way for a few weeks.  On this one particular machine, I'm having to use the nvidia backend  one of the ck's, but most of the other machines are intel/libgl/whatever it's called now...could be the nvidia backend doing that weird stuff with my fonts.  I think the monitor is reporting some funny EDIDs and that could also be part of the problem.  But some applications show normal size fonts, while others are fixed at small way too small to be readable even at recommended resolution for the monitor.

Re: [SOLVED] Extreme blurry fonts in some applications

Hi you all,

sorry I realy forgot to look here for answers again!

Thanks for all your Ideas!

Any chance you can post the actual pdf output of LaTeX?

I could - but in fact I fear it is not really helpful...
The internal pdf-viewer of TeXStudio and Okular also render the font very blurry. But in evince it looks quite good.

I made some further observations:
1. The font is rendered correctly in other DEs (Cinnamon, LxQt)
2. The font is rendered correctly when not using my NVIDIA-driver (but I have to use it because of battery-life and triple-monitor-setting)

Evince reader does not have this problem.

...as described: Same for me...

Setting display scaling to 1 in KDE system settings and increasing font dpi fixes this issue for me.

I'll try this ;-)

@nomorewindows I also think, it has to do with the nvidia-stuff...

Thank you so much!
I've tried a hundreds different solution approaches, but nothing helped.

Setting scaling to 1 was the solution!

Now I can my favorite Desktop Environment :-D

Yes, it looks like this.
But actually I do not really need this scaling-option.

Therefore I would just close this thread (?)

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan
