Re: Missing text in gui apps on Kubuntu

Wed, 10 Jun 2020 00:32:03 -0700

Got yesterday's KDE Neon release installed successfully [1], and the missing-text issue Patryk found on Neon/Aarch64 also affects Neon/ x86_64: GNUstep gui apps are missing all UI text characters except digits.
Running the fc-pattern-check tool on Neon (attached output: fcpc_out_kdeneon.txt) shows the same issue as on Kubuntu: The second FcFontMatch() call returns a match for the "Noto Color Emoji" font. 

Cheers,

Josh

Thank you Josh for this excellent analysis. My impression is that  
this is somewhat of a Kubuntu bug, still it is better to fix it in  
our code especially if this results in a speed up. Such a speed up  
is really needed for slower machines.


I will look through the details of the patch tomorrow and apply it.

Cheers,

 Some users of Kubuntu (official flavor of Ubuntu with the KDE  
Plasma desktop) reported that PikoPixel's missing most of its UI  
text; Numbers are the only characters displayed:

https://old.reddit.com/r/Kubuntu/comments/gas88l/pikopixel_strange_graphics_bug_any_suggestions_on/


 I can reproduce this on Kubuntu 20.04, and the missing-text issue  
affects all GNUstep gui apps, whether the apps & GNUstep are from  
packages or from current sources.



 This might be the same issue that Patryk found last August with  
KDE Neon:

https://lists.gnu.org/archive/html/gnustep-dev/2019-08/msg00019.html

 (I couldn't test this, because the current x86_64 builds of KDE  
Neon fail to install on a VirtualBox VM, and older versions don't  
seem to be available).



 Manually installing a different desktop on Kubuntu doesn't fix the  
issue; Text is still missing on GS gui apps when run under GNOME or  
Window Maker, however, switching GS's backend from Cairo to Art  
fixes the text.



 Text displays correctly on Ubuntu 20.04 - even under Plasma - and  
also on a daily build of Ubuntu Studio 20.10 (Plasma is Studio's  
installed desktop as of 20.10).


 The issue's caused by a combination of two factors:


A) The Cairo backend sets up fontconfig patterns for font matching  
by calling the fontconfig library's Fc...Substitute() functions  
twice on each pattern instead of once:
 The backend's FCFaceInfo class has two methods, matchedPattern &  
characterSet, that each call FcConfigSubstitute() &  
FcDefaultSubstitute(), passing the FCFaceInfo instance member,  
_pattern, to be modified. Both methods in turn are called from  
within a single method, -[CairoFontInfo setupAttributes] (itself  
called from the FcFontInfo initializer):
 1. [CairoFontInfo setupAttributes]:[FcFontInfo (super)  
setupAttributes]:[FCFaceInfo characterSet]
 2. [CairoFontInfo setupAttributes]:[CairoFaceInfo fontFace]: 
[FCFaceInfo matchedPattern]
 Note that the font face is only generated after the second set of  
Fc...Substitute() calls.



B) The fontconfig library's font-matching functionality behaves  
differently on Kubuntu vs. other distros (even with the same  
version installed - Kubuntu 20.04 & Ubuntu 20.04 both have  
libfontconfig1 2.13.1-2ubuntu3).




 Alone, neither factor causes the issue, however calling the  
Fc...Substitute() functions twice on the same pattern on Kubuntu  
leaves a modified pattern that - when passed to FcFontMatch() -  
always resolves to the "Noto Color Emoji" font. (That font has no  
alphabet characters, but does have digits, which explains why only  
numbers appear in the above linked screenshots).



 To demonstrate this, the attached C file, fc-pattern-check.c,  
builds a standalone diagnostic tool using only the fontconfig  
library - no GNUstep. It creates a fontconfig pattern for matching  
the "DejaVu Sans" font and makes two sets of calls to  
Fc...Substitute() & FcFontMatch(), duplicating the calls made by  
the Cairo backend. After each call, the resulting pattern is printed.



 The attached textfiles, fcpc_out_kubuntu.txt &  
fcpc_out_ubuntu.txt, are the outputs from running the fc-pattern- 
check tool on Kubuntu 20.04 & Ubuntu 20.04.



 Comparing the two output files, the first difference comes after  
the first call to FcConfigSubstitute(): On Kubuntu, the pattern has  
a "rgba" (pixel-format) field inserted - this may not contribute to  
the incorrect match, but it already shows a different behavior  
between Kubuntu & Ubuntu.



 Following the first set of Fc...Substitute() calls, the first call  
to FcFontMatch() correctly returns a resolved pattern for the  
"DejaVu Sans" font on both Ubuntu & Kubuntu. When these same first  
calls are made by the Cairo backend, the resolved pattern's used  
only to get the font's character set, not to generate the font face  
for drawing.



 After the second call to FcConfigSubstitute() on Kubuntu, the  
pattern's "lang" field for some reason now contains "und- 
zsye" (emoji locale) before its earlier value, "en" (english). The  
pattern now also contains a "color" field with a value of  
"True" (requiring a match to a font that contains color  
information). With those field values present, the second call to  
FcFontMatch() returns a resolved pattern for "Noto Color Emoji"; On  
Ubuntu, its second FcConfigSubstitute() call doesn't add those  
"lang" & "color" values to the pattern, and its second call to  
FcFontMatch() correctly returns a "Deja Vu Sans" resolved pattern.




 The attached patch, libs-back_fontconfig_pattern_fix.diff, fixes  
the missing text by limiting FCFaceInfo's Fc...Substitute() &  
FcFontMatch() calls to once per pattern. The resolved pattern  
returned by FcFontMatch() is now stored in FcFaceInfo's _pattern  
member (which previously only held a pre-matched pattern), and a  
new bool member, _patternIsResolved, keeps track of _pattern's pre- 
matched/resolved state.



 The characterSet method now gets the resolved pattern by calling  
the matchedPattern method instead of calling the fontconfig  
functions directly; Outside of the initializer, dealloc, &  
matchedPattern methods, the _pattern member is now only accessed by  
the displayName method (which just reads the pattern's fullname,  
postscriptname, & style fields - if those were present in the pre- 
matched pattern, they should remain in the resolved pattern), so  
there should be no side-effects from storing a resolved pattern  
instead of a pre-matched pattern in the _pattern member.



 Loading a large set of fonts will probably also go faster now, as  
FcFontMatch() is only called half as often.


Cheers,

Josh
