The screenshot says it all. Kdiff3 stopped working (I don't know it it's KDE 3.4 related, because I haven't used it for some time). The window is completely unusable because of the rendering flaws. This is the only program which exhibits such a behaviour, everything else works perfectly well. I have tried re-emerging the program, but I still get the same thing. http://www.netpalantir.it/resserver.php?blogId=1&resource=snap16.jpg Reproducible: Always Steps to Reproduce: 1. Just start KDiff3 2. 3.
There's some problem at a lower level for sure, it's really strange that it only happens with kdiff3... Please post your 'emerge info', the version of kdiff3, qt, xorg-x11, etc...
Are you using some experimental xrender extension, maybe?
The "extension" word remindend me something :-) I had tried some time ago with xcompmgr, but it didn't work (because of the incompatible ati-drivers). So I disabled it from the KDE control center, but forgot to revert the change I made to xorg.conf, i.e. the composite extension was still enabled: Section "Extensions" Option "Composite" "Enable" EndSection Commenting out that, makes kdiff3 work again. However, it is very strange that kdiff3 is the one and only application that has problems with this... I post my configuration anyway, just in case you were curious ;-) kdiff3 version: 0.9.88 kde version: 3.4.0 ati-drivers version: 8.12.10 ----------------------------------------------------------------------- piastrella [98%] ~ $ X -version X Window System Version 6.8.2 Release Date: 9 February 2005 X Protocol Version 11, Revision 0, Release 6.8.2 Build Operating System: Linux 2.6.10-gentoo-r4 i686 [ELF] Current Operating System: Linux piastrella 2.6.11-gentoo-r4 #1 Wed Mar 30 20:09:19 CEST 2005 i686 Build Date: 07 March 2005 Before reporting problems, check http://wiki.X.Org to make sure that you have the latest version.
