showimg 0.9.4.1 running on top of KDE 3.3.2 never manages to display the thumbnails in the thumbnail browsing pane. All other images are displayed correctly. The problem appears whatever size is used for thumbnails. If thumbnails are toggled off, the generic icons used show the same behaviour. I have notified the developer. As it is showimg isn't useable. Reproducible: Always Steps to Reproduce: 1. start showimg 2. browse a directory with images 3. urk My system is mostly stable packages, especially on the library side. There is a discussion on this issue and related ones at http://forums.gentoo.org/viewtopic-t-300921-start-0.html where some feel that the qt libs are at fault somehow although the bug only appears in showimg (I tried a lot of similar applications). ix root # emerge info Portage 2.0.51.19 (default-linux/amd64/2005.0, gcc-3.4.3, glibc-2.3.4.20041102-r1, 2.6.11-gentoo-r6fred x86_64) ================================================================= System uname: 2.6.11-gentoo-r6fred x86_64 AMD Athlon(tm) 64 Processor 3000+ Gentoo Base System version 1.4.16 Python: dev-lang/python-2.3.4-r1 [2.3.4 (#1, Apr 27 2005, 23:25:57)] dev-lang/python: 2.3.4-r1 sys-devel/autoconf: 2.13, 2.59-r6 sys-devel/automake: 1.8.5-r3, 1.5, 1.7.9-r1, 1.6.3, 1.4_p6, 1.9.4 sys-devel/binutils: 2.15.92.0.2-r7 sys-devel/libtool: 1.5.14 virtual/os-headers: 2.6.8.1-r4 ACCEPT_KEYWORDS="amd64" AUTOCLEAN="yes" CFLAGS="-O2 -march=k8 -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.3/env /usr/kde/3.3/share/config /usr/kde/3.3/shutdown /usr/kde/3/share/config /usr/lib/X11/xkb /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O2 -march=k8 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs autoconfig ccache distlocks sandbox strict" GENTOO_MIRRORS="ftp://cs.ubishops.ca/pub/gentoo ftp://mirror.iawnet.sandia.gov/pub/gentoo/ ftp://ftp.belnet.be/mirror/rsync.gentoo.org/gentoo/ ftp://planetmirror.com/pub/gentoo/ ftp://mir.zyrianes.net/gentoo/" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="amd64 X acpi alsa arts berkdb bitmap-fonts bluetooth cdr crypt doc dvd dvdread emul-linux-x86 encode esd exif fam ffmpeg font-server fortran gif gnome gphoto2 gpm gtk gtk2 ieee1394 imagemagick imap imlib ipv6 jp2 jpeg kde ldap lm_sensors lzw lzw-tiff mime motif mozilla mp3 ncurses nls offensive ogg opengl oss pamperl png python qt readline samba scanner session spell ssl svg tcltk tcpd threads tiff truetype truetype-fonts type1-fonts unicode usb userlocales v4l vcd vorbis wmf wxwindows xine xml2 xosd xpm xrandr xv xvid zlib" Unset: ASFLAGS, CBUILD, CTARGET, LANG, LC_ALL, LDFLAGS, LINGUAS, PORTDIR_OVERLAY
Ditto. I'm running Xorg 6.8.2-r1, Qt 3.3.4-r2, and KDE 3.4.
has anyone notified the auther of the software of this issue? I tried to send him an email, though without success ...

Hey Folks, they author of showimg, Richard Groult, actually got back to be on my email. Bottom line was, he has no idea about the problem, since it only seems to occur on Gentoo systems. If you'd like more detail, here's our conversation so far: ******************************************************************** Hello Richard, since there were no follow ups to the forum post discussing this problem, I decided to contact you directly. When using showimg on my machines kde-3.3.2 / kde-3.4, qt-3.3.4, Gentoo Linux, the thumbnails fail to display. The only way to get them visible is to scroll the thumbnail bar up and down. Thereafter they fail to redraw and vanish again, if they are touched with the mouse or covered by another window. The forum post http://listes.jalix.org/wws/arc/showimg-users/2005-03/msg00005.html also describes the issue pretty well, though I do not agree that this is a kde/qt bug, since the problem only seems to appear in showimg, and possibly some kpat game. I agree however, that the issue is likely qt related, since it manifested when updating from qt-3.3.3 to qt-3.3.4. Might it be possible that showimg has problems with certain compile flags? That seems to be a reasonable question, since problems tend to appear mostly on Gentoo systems. I'd much appreciate any ideas, since - but for this awful issue - showimg is still the most comfortable image viewer out there.

Unfortunatly, I have no idea because it seems specifics to the gentoo... have you more information about other softwares having this pb? -- Richard GROULT IRC: irc.freenode.net, #showimg ShowImg: http://www.jalix.org/projects/showimg/ List: http://listes.jalix.org/wws/arc/showimg-users Web: http://ric.jalix.org/ ******************************************************************** Hey Richard, thanks for getting back to me. This thumbnail refresh issue is somewhat hard to nail down, since Gentoo is a meta-distribution and people do not generally have the same setup. From the Gentoo Forums i gather that not everyone suffers from this issue. Strangely enough no other application has this kind of issue on my machine. I only read in the forums that "kpat" supposedly has this problem. I still have to try that on my other machine at home ... on this one i don't have the application. What kind of mechanism do you use to display thumbnails? It must differ substantially from all other kde apps since none of those is broken on my system. I just verified, that it has nothing to do with gcc flags and optimizations, since the issue occurs even when switching to CFLAGS="-O1 -pipe" CXXFLAGS="${CFLAGS}" I attached the compilation log ... hope it is good for something though i doubt it ... The Gentoo Bug associated with this issue is http://bugs.gentoo.org/show_bug.cgi?id=90758 I will post our conversation there, maybe other people know something .... More information on the issue can also be found on http://forums.gentoo.org/viewtopic-t-333460.html http://forums.gentoo.org/viewtopic-t-300921.html If there is some specific information I could provide to help resolve this problem, please let me know! Best Regards Nik
Can all of you having this problem confirm that it does not happen with qt-3.3.3-r1, and it happens with qt-3.3.4? That would be a good starting point...
(In reply to comment #5) > Can all of you having this problem confirm that it does not happen with > qt-3.3.3-r1, and it happens with qt-3.3.4? > That would be a good starting point... It is 3.3.4-r3 that I have installed here, haven't tried it with 3.3.3-r1 (which is ~ masked on amd64). I tried kpat though (mentionned above as having similar problems) and it appeared to work normally, no display problems that I could see.

I'm having the same problem with showimg. This first happened when I upgraded to qt-3.3.4-r3. I'm willing to downgrade qt to see if the problem remains. But what things will have to be recompiled? I'm running kde-3.3.2. Will recompiling kde-base and kde-libs be enough?

I have installed qt-3.3.3-r1 and showimg works perfect. I did have to recompile kdelibs. Showimg wasn't installed on my system, when I tried to emerge it, i got an error that kdelibs wasn't installed. Reemerging kdelibs and than emerging showimg worked. I hope someone can make a fix so that showimg works with more recent versions of qt.
Thanks Mathias. Wild guess: can someone try (if he could reproduce the bug) to recompile qt-3.3.4, but commenting out the lines in the ebuilds that apply the "flickerfree_qiconview_buffered" patch and the "flickerfree_qscrollview_fixwindowactivate" patch first?

Commented, and ... it works! Thumbnails and icons in the thumbnail browsing panel or Ok. Not need to recompile anything else.
(In reply to comment #11) > >Wild guess: can someone try (if he could reproduce the bug) to recompile > Commented, and ... it works! Thumbnails and icons in the thumbnail browsing > panel or Ok. Same here, commented and recompiled qt-3.3.4-r4. Showimg is working as it should.
Patches removed from the Qt ebuild. I will use this bug as a reference in future when we are asked to include 3rd party patch in our ebuilds ;)
