The exact same architecture? Particularly, same gfx card and same version of said driver for said card, with same xorg.conf config options? It's just the perennially annoying closed x11 drivers for ati/amd and nvidia hardware often have bizarre 2D drawing glitches, and they can be dependent on the precise version, configuration options (like which AccelMethod is in use) and whether compositing is enabled [1][2] (in contrast, the open drivers are typically slow for 3D but really good for 2D) > 2 No other applications seem to be affected this way on the box. That _could_ be just luck / the subset of apps used by the driver authors for testing coinciding with yours. Emacs handles its own drawing to the main window with direct xlib calls, and may do things legally but still differently to some other apps. > If I use the same emacs installation forwarding X output to another machine it > works fine. Well, as Eli points out, that does strongly suggest it's an X server level problem, not an emacs problem. If it were, say, some call to XFillRectangle being misplaced in the emacs binary you'd expect it to occur on all X servers you tried. The chances of DejaVu Sans Mono metrics being messed up seem slim, and also xft/xrender based font rendering, unlike the old core x11 server-side font rendering, uses client-side tesselation to trapezoids and you say the same emacs works on another x11 server, so that's not the problem. While it's been actively developed (descended from Bitstream Vera) and therefore there are different versions of it floating about, it's an extremely widely used font, and the one I use with emacs with no such problems.
