OK, I get the same issue. But if you change the font size, thus: <pre style="background-color: white; font-size:105%;">softpoint_with_block() { the underscores are visible.

This looks like a bug in the font: http://dejavu-fonts.org/wiki/Bugs/Archived (you need to scroll down a bit). I have version 2.34 installed - will see if I can reproduce it later.

I am using "Liberation Mono", but with "DejaVu Sans Mono" have the same problem. It is probably because of the characters height - the next row of text overwrites the previous. The question is whether this is because of Dillo or because of FLTK. The same font, used in Firefox renders correctly. -- http://fresh.flatassembler.net http://asm32.info John Found <johnfound at asm32.info>

I have not set any specific font in dillorc, so the default setting is used. However, when I change the monospace font to font_monospace="Monospace" then the rendering problem disappears and the underscores are correctly displayed. When I change to font_monospace="DejaVu Sans Mono" the rendering problem is present, i.e. the underscores are not displayed.

Change your default font to something else and see what happens. Also check FLTK's test programs (IIRC there's a symbols one, and another that's useful to try fonts). If FLTK also has problems check the video driver (older kernel, older/different video driver, GRUB CLI parameter). -- Cheers Jorge.-

Hi Jorge, then maybe it is an FLTK issue? I'm using Debian Jessie GNU/Linux 4.6.0-0.bpo.1-amd64 FLTK 1.3.1 Best regards, Alex On Thu, Jul 21, 2016 at 08:14:20PM -0400, Jorge Arellano Cid wrote: > Hi Alexander, > > On Thu, Jul 21, 2016 at 09:50:22PM +0200, Alexander Voigt wrote: > > Hi Dillo developers, > > > > I stumbled upon a page with a lot of code snippets wrapped in a <pre> > > block, where Dillo seems to have a rendering problem: Underscores `_' > > are not drawn.

The attached example renders OK here. Maybe someone else can reproduce it. -- Cheers Jorge.-
