Description Mary Ellen Foster 2008-10-24 19:18:41 UTC
Created attachment 321459 [details]
System settings window (note title bar)

Description of problem:
I'm running F10 rawhide on an Acer One mini-laptop with a DPI of 133x135 (according to xdpyinfo). It seems that the fonts in window title bars, the start menu, and the task bar are using a different DPI than the rest of the system: they show up as significantly smaller than what is ostensibly the same font inside windows.

I'll attach a screenshot of the system settings dialogue -- note the difference between the 9-point text in the "Window title" field and the actual window title bar.

Version-Release number of selected component (if applicable):
kdebase-workspace-4.1.2-6.fc10.i386

Comment 1 Rex Dieter 2008-10-24 19:28:40 UTC
odd, can't reprduce here.

So, do window title bar fonts change, just are always a little smaller (when changing setting in systemsettings)?

Comment 2 Mary Ellen Foster 2008-10-24 20:10:19 UTC
Yes, they change size if I change them in the settings. I suspect that the kwin fonts are using something like 96dpi whatever the actual dpi setting of the display is.

You can probably reproduce this by temporarily changing the DPI in the kdm config -- say, add "-dpi 135x135" to the ServerArgsLocal in /usr/share/config/kdm/kdmrc and seeing what happens to the fonts. I predict that the taskbar and titlebar fonts will not change but that everything else will get tiny.

NB: the fonts may get huge instead of tiny -- not entirely sure -- but the relevant thing is that the titlebar won't change.

Comment 4 Mary Ellen Foster 2008-11-13 06:48:08 UTC
It looks like the latest update to kdebase-workspace -- kdebase-workspace-4.1.2-14.fc10.i386 -- has fixed this issue. I can't see anything specific in the changelog that would have done it. Maybe it was some other update instead ... anyway, closing.

Comment 5 Mary Ellen Foster 2008-11-13 07:36:02 UTC
Oops, spoke too soon. Things were good *once*, but then I restarted and it's back to tiny fonts again. I wish I knew what had produced that one working configuration ... :(

Comment 6 Bug Zapper 2008-11-26 04:12:56 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.

Comment 7 Mary Ellen Foster 2008-12-18 07:38:10 UTC
I just discovered a workaround -- if I use the fonts systemsettings module to "force fonts DPI" to 120 (or to 96 too, probably, but that's even further from reality), the kwin and non-kwin fonts seem to agree with each other. This also fixes a problem I was having with GTK gui elements that (I assume) come up as root -- like the "you are now connected" popup from nm-applet -- coming up with *huge* fonts.

So this feels sort of like a hack, but I think it's the best solution for the moment. (NB: all fonts look good in Gnome ... :( )

Comment 8 Mary Ellen Foster 2009-01-07 21:02:29 UTC
Should I file this upstream? Fonts are basically okay on my laptop (natural DPI 98x98), but on a couple of laptops with higher-resolution screens (133x135 and 129x129) there's a *very* perceptible difference between the desktop font sizes and the font sizes inside windows.

Comment 9 Rex Dieter 2009-01-07 21:08:05 UTC
yes, please do.  We'll definitely need some guru-type assistance to track this down.

Comment 10 Steven M. Parrish 2009-01-09 21:02:10 UTC
Thanks for reporting this upstream.  Going to close this as UPSTREAM and will monitor for resolution.
