Please write in English if possible, because the Emacs maintainers usually do not have translators to read other languages for them. Your bug report will be posted to the address@hidden mailing list. Please describe exactly what actions triggered the bug and the precise symptoms of the bug: I use Emacs.Font: DejaVu Sans Mono-10 set in my .Xdefaults and get quite a lot display problems. I update my copy of emacs nearly daily (with make maintainerclean and all), and my subjective feeling is that in the last 3 or 4 days I have much more problems. The most frequent problem is that individual chars look wrong, for example: - quite often a "w", "k", "S" or "r" looks bold although it shouldn't - "m" has a green shine between its legs - fonts aren't sharp as if subpixel hinting was disabled The attached pics fonts{1,2,3,4}.png show some of those minor display problems. While trying to find some more of those display problems I opened the attached UTF-8 testfile and found a major display bug. The pics v-with-dot.png and v-with-dot2.png show it. In v-with-dot.png the text is more or less displayed correctly. The dots over the v and r are displayed a bit higher using kwrite with the same font, which looks a bit more natural. Point is left of the text on the same line. Now I move point to the right and as soon as it passes the v, a and b they're duplicated to the left, resulting in the situation in v-with-dot2.png. Additionally in that file most greek chars aren't antialiased. If Emacs crashed, and you have the Emacs process in the gdb debugger, please include the output from the following gdb commands: `bt full' and `xbacktrace'. If you would like to further debug the crash, please read the file /usr/share/emacs/23.0.60/etc/DEBUG for instructions.
