Bug 15161 – major rendering slowdown (gnome and kde) after xfree upgrade

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Artur Brodowski 2003-02-05 07:55:19 UTC]

after upgrading xfree to 4.2.99.4 i've noticed horrible rendering problems.
at first gdm would not start, all i got was empty X screen with new busy cursor.
i've tried to run gnome-session without gdm, but every time something new is
drawn on the screen it takes _seconds_for_every_widget_. gnome starts for about
20 minutes! i even emerged latest kde, since i thought it was some
bonobo-activation prob, but kdm and startkde behave the same way as gnome.
strange thing is, that window that is already drawn is responsive, can be moved
as fast as usual; only new windows/menus/etc take ages to show up. they also eat
up to 100% cpu when rendered.
this happens only to 'modern' desktops, xdm, xterm, lwm - they all run nice and
fast. that's why my first thought was freetype/xft/fontconfig. i tried to
remerge them, stable and latest version, neither helped.
i found in xfree ebuild changelog, that it breaks font cache on ppc, but that's
different (i've emerged qt and kde _after_ upgrading xfree). i suspect font
rendering problems though.

Reproducible: Always
Steps to Reproduce:
1. upgrade xfree
2. start gdm/kdm or gnome-session/startkde
3.

Actual Results:  
next day (new xfree loaded) everything takes long, long time to render. even
refreshing webpage takes minutes. this does not happen to older software, xterm,
lwm, even gtk1.2 apps. probably aa-related issue.

Expected Results:  
well, it should run as fast (or even faster due to improved xfree) than before.

[ebuild   R  ] x11-base/xfree-4.2.99.4
[ebuild   R  ] media-libs/fontconfig-2.1-r1
[ebuild   R  ] x11-libs/xft-2.0.1-r1
[ebuild   R  ] media-libs/freetype-2.1.3-r2
i've tried to remerge last three in different ways (stable/latest versions),
it does not help.

looks like it's xft issue after all, see #15188
