I have upgraded to recent pixman and my fonts rendered in xdm login window, but later on also in opera, seamonkey were not readable. Luckily, not affected were fonts in xterm. I have recompiled freetype, cairo but no luck. In the end I can conclude that the cause is upgrade to pixman-0.11.4. emerge.log does not record (I believe anymore) the previous version being unmerged. Stepping back to 0.10.0 fixes the bug and recompilation of 0.11.4 re-introduces it again. I tested gcc-4.2.4 and 4.3.1, the bug appears with pixman lib produced by both. I have the following CPU: $ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Mobile Intel(R) Pentium(R) 4 - M CPU 1.80GHz stepping : 7 cpu MHz : 1200.000 cache size : 512 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe pebs bts sync_rdtsc bogomips : 2401.27 clflush size : 64 And from the compile message I pick some which might be related to identify the cause: >>> Emerging (1 of 1) x11-libs/pixman-0.11.4 to / * pixman-0.11.4.tar.bz2 RMD160 SHA1 SHA256 size ;-) ...

Both pixman libs configure scripts decide to use only MMX and SSE2, not SSE. Maybe that is not a bug with configure at all, a just thought. Definitely, my system does support these cpu flags. I did not have a look but hope the ebuild would filter out -msse3 CFLAGS if I would have had one.

Hanno already mentioned this on the xorg mailing list. It would also help if you'd file a bug at bugs.freedesktop.org in the xorg product, because we won't be doing the fixing here. Please search for / file a bug and reopen this one once it's resolved upstream.

same here on amd64
I just masked pixman 0.11* till this gets fixed.
--- Comment #4 from Søren Sandmann Pedersen <sandmann@daimi.au.dk> 2008-06-26 09:22:45 PST --- In pixman-0.11.6, the sse2 fast path code can be disabled at configure time: configure --disable-sse2 If someone could test and see if this makes the bug go away, that would be interesting. Also interesting would be to know whether the bug depends on font rendering configuration, in particular whether it happens when the font is set to something other than subpixel antialiasing.

Newer ebuilds have some logic in place to make sure you don't use sse2 without the correct compiler. Fixed
