It's a Debian system with XFree 4.3.0.dfsg.1-14 and according to lspci I have 0000:01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV100 QY [Radeon 7000/VE] > If you're feeling adventurous, you can rebuild Tk with the patch below > (courtesy of D.

I list my steps for people who want to "fix" it, too: Note: You need a deb-src line in your sources.list. Moreover some packages are assumed to be installed (e.g. devscripts, fakeroot, vim :-)) ~$ mkdir src; cd src ~/src$ apt-get build-dep tk8.4 ~/src$ apt-get source tk8.4 ~/src$ cd tk8.4-8.4.12 ~/src/tk8.4-8.4.12$ vim generic/tkCanvUtil.c [ apply the patch provided by Paul/D. Richard Hipp ] ~/src/tk8.4-8.4.12$ dch -n [ write a sensible changelog entry ] ~/src/tk8.4-8.4.12$ fakeroot dpkg-buildpackage ... ~/src/tk8.4-8.4.12$ cd .. ~/src$ sudo dpkg -i tk8.4_8.4.12-1.1_i386.deb I'm not entirely clear what this patch does. From only reading it, I assume it should only have an effect on rather big windows, right? Do you know some more details about the bug? Do you know to who it should get reported?
