Description piedro 2015-10-20 09:17:53 UTC

As I am have some problems with my eyesight, I changed all fonts to Oxygen-Sans and set them to bold. 
Also I increased the font DPI to 144 in hope this would scale my whole Ui. That last part works surprisingly well, apart from some elements not increasing the line height of text rows though the font is rendered bigger than the height of the row.... (in the search that opens with ALT+F2 for example)

The problem in systemsettings is that the subsettings menu (the left sidepanel) clearly uses different font rendering than the main setting in the middle of the screen. 

For example open Systemsettings , go to "applications". 
In the left sidepanel you get 4 sub items like "places" or "default applications". These items use a different font rendering than the settings in the main part of the KCM... 

I can't be more specific, the left panel fonts seems to be not bold at all or it might not be the same font I cannot tell. The same problem also shows in the middle element of amarok and in some other KDE applications which use this kind of sidepanel-with-big-symbols-submenu approach... 

thx for looking into it, p.

Reproducible: Always

Is the problem only visible with the oxygen font? I suggest to add screen shots.

If you can provide the information requested in comment #1, please add it.

Sorry I cannot help anymore, it's been some time now and I had to work with the machine here.

I replaced all fonts again with Cantarell. Also tried Noto Sans. These seem to be better.

I do not use Amarok anymore for that reason. It still seems (I just tried to answer your question) that the middle pane uses all kinds of fonts and sizes, certainly it doesn't respect system fonts but I do not care anymore...

Within systemsettings the side panes seem to use the same font and styling now which is Noto sans.

I am sorry not to be more helpful but I had to come up with a solution quick, changed the screen resolution from 1920x1200 to 1440x990 and forced 96 DPI (which is wrong - my monitor physically has 82dpi!) then changed all fonts to the gnome fonts. Now everything looks different but I can work with it and I do not have the inconsistencies described...

I cannot change back now to the old setup for the bug hunt. I regret that as I am always very unhappy that so many bugs aren't handled at all. Now you are looking into this and I can't provide more detail.

It's a shame I cannot be more helpful. If you want you can delete this bug and wait whether someone else finds this again. Maybe this all goes away anyway with the next updates...

As a "worth trying" workaround (for those who have problems with font consistencies) I recommend using the gnome fonts: Cantarell, Ubuntu, Noto.... These seem to render more consistent than the KDE defaults... but maybe this is just my setup.

thanks,
piedro

I do not see this behaviour anymore, working on plasma 5, KF 15.20 on Arch fully updated... 

So as far as I am concerned this is resolved, anyone?

Screenshot of the issue

I've ran into this today. You can clearly see the missaligned top part of the letters in the menu My version of the application is:
Application: systemsettings5 (5.12.4)
Qt Version: 5.9.3
Frameworks Version: 5.45.0
Operating System: Linux 4.13.0-38-generic x86_64
Distribution: KDE neon LTS User Edition 5.12

After trying to search for a built in report button, the application crashed. The bug reporter claimed that my crash report isn't useful, but I searched for the fonts bug and came here.

I was using Noto Sans 15 or 14 for my fonts. Changing the fonts to Ubuntu of the same size didn't alter system settings and the behaviour persisted.

Comment 6 Christoph Feck 2018-05-10 00:07:23 UTC

The original issue is no longer reproducible.

Comment #5 is bug 393724.
