recent libx* upgrade issues

Hi all!

I upgraded a number of packages today on my laptop today.  I upgrade often so this wasn't a huge upgrade.  After rebooting, I noticed that xmessage and xclock were using lots of CPU (about 60% of a core each), and that rxvt-unicode (Monaco font) was much wider than it used to be.  I tried downgrading the kernel and nvidia driver, no change, so I reverted to the latest versions again.  Then I downgraded the recent libx* upgrades, specifically:

libxext (1.3.1-1 -> 1.3.0-2)
libxxf86vm (1.1.2-1 -> 1.1.1-2)
libxxf86dga (1.1.3-1 -> 1.1.2-2)
libxv (1.0.7-1 -> 1.0.6-2)
libxvmc (1.0.7-1 -> 1.0.6-2)
libxtst (1.2.1-1 -> 1.2.0-2)
libxt (1.1.2-1 -> 1.1.1-2)
libxss (1.2.2-1 -> 1.2.1-2)
libxres (1.0.6-1 -> 1.0.5-2)
libxrender (0.9.7-1 -> 0.9.6-2)
libxpm (3.5.10-1 -> 3.5.9-2)
libxmu (1.1.1-1 -> 1.1.0-2)
libxkbfile (1.0.8-1 -> 1.0.7-2)
libxinerama (1.1.2-1 -> 1.1.1-2)
libxft (2.3.0-1 -> 2.2.0-2)
libxdmcp (1.1.1-1 -> 1.1.0-2)
libxcursor (1.1.13-1 -> 1.1.12-1)

Which fixed both the high CPU for xclock and xmessage and the "wide font" issue.  xclock and xmessage are used by the xdm-arch-theme package from AUR.

I'm using i686 and my (Dell) laptop has an NVidia 8600M GT.

Has anyone else experienced this?

Re: recent libx* upgrade issues

I use xclock in Openbox on my x86_64 system, and I don't notice any higher cpu usage with it after updating to the last versions of these libx* packages.
I don't use xdm.
Have you tried without the xdm-arch-theme package?

Re: recent libx* upgrade issues

Hi!

I can confirm the font issue. (rxvt-unicode, DejaVuSansMono font) Downgrading libxft solved it.

I made some screenshots to compare the situation after and before upgrade:
FluxBB bbcode test

Found this:
http://cgit.freedesktop.org/xorg/lib/libXft/tree/NEWS

Version 2.3.0

Subpixel LCD text rendering improvements

I think the subpixel rendering improvements are guilty here (you can zoom in the image to see the effect).

Cheers!

Re: recent libx* upgrade issues

The new version of libxt also breaks xscreensaver.  It outputs corrupted graphics and the CPU hits 100%.  Rebuilding screensaver does not wok but downgrading libxt fixes it.  These a bug report regarding another problem too - FS#28844.

Re: recent libx* upgrade issues

Are you all running old Xorg from extra? I don't see anything broken on my testing systems with recent Xorg.

Re: recent libx* upgrade issues

I can confirm the urxvt issues with libxft 2.3.0-1. Downgrading to libxft 2.2.0-2 helped.

I do not see that here: xscreensaver works the same as before the upgrade to libxft 2.3.0-1 and libxt 1.1.2-1.

Re: recent libx* upgrade issues

The problem I now have with xscreensaver after these upgrades, only involves specific screensavers that must load images from a user-defined location (GLSlideshow, photopile, etc..)  Xscreensaver returns:

Warning: Select failed; error code 5

Re: recent libx* upgrade issues

Hi all,

Thanks for the input - libxft downgrade has certainly sorted out the urxvt font width problem.  Alas, xclock and xmessage still use high CPU, though I've managed to narrow it down to one (or maybe all) of these three:

libxmu
libxext
libxt

Reverting to earlier versions of these stops xclock and xmessage high CPU usage.

Ignore this post, I misread the previous post.

Re: recent libx* upgrade issues

Had to downgrade and freeze libxft, too. The fonts on urxvt were unbearable - unfortunately terminus doesn't do a good job in rendering some accented characters, otherwise that's what I'd be using. Terminus rendering didn't break with the upgrade, it only happened with some fonts - Bitstream Vera Sans mono in my case.

Re: recent libx* upgrade issues

libxt 1.1.2-2 fixes the problem with xscreensaver.

Re: recent libx* upgrade issues

libxt 1.1.2-2 has fixed the xclock and xmessage problems for me as per https://bugs.archlinux.org/task/28844

However, libxft 2.3.0-2 does not fix the wide fonts issue.

Re: recent libx* upgrade issues

I’d also like to confirm the same here. My ~/.Xresources has

URxvt*font:             xft:Bitstream Vera Sans Mono:pixelsize=13:antialias=true

and urxvt gets wider with libxft-2.3.0-2 than with libxft-2.2.0-2. Downgrade helped.

Re: recent libx* upgrade issues

I don't have this problem and one thing I notice is that I have antialias off myself, everybody else with the issue seems to have it on. So I guess it's probably not linked to the font/size, but antialiasing...

Re: recent libx* upgrade issues

Yup, I confirm. Only antialiased fonts are wider.

jjacky & Onyros, you are right, if I turn off antialiasing, I don’t have the width problem, however fonts become unbearably ugly…

Re: recent libx* upgrade issues

Subpixel rendering improvements are the most probable culprit. If an update to inconsolata solved the issue, it'll be a matter of time until other fonts having problems catch up.
