[Bug 770707] Re: Kerning error in outline rendering
This is actually a bug with qtwebkit (which I think they've since fixed
but not yet released).
I thought I had managed to workaround it, but you seem to have found an
example which fails.

Title:
Kerning error in outline rendering
Status in OpenLP - Worship Presentation Software:
New
Bug description:
Currently the outline rendering uses a kerning different from the 'shadow' one. Thus it happens, that the 'outline characters' and the 'shadow characters' are shifted towards each other.
To show the effect one has to create a theme with a outline. It depends on the words if this happens. So you might have to look at a couple of different slides.
Sample configuration: Main area font: DejaVu Sans | 34pt | bold | outline 1pt
It looks, that there are basic differences in the kerning algorithms, as the problem is strong at characters like a capital 'T' followed by a half height letter.
