When using a bigger default font, the checkboxes start to disappear under the baseline. The "down.svg" does not have this issue. I've start to wonder if it is a bug in librsvg on my system but I can see that it is used by blender, gimp, vlc… So I think I would have seen this bug elsewhere. Maybe it is a bug that arise with the combination of "checked.svg" and librsvg? But I think it is not something that shows on Linux. What do you think I could test, now? -- Manuel Giraud
