Disabling hardware acceleration also screws up font anti-aliasing

As in title.

First screenshot shows what happens with hardware acceleration enabled, which looks better, second screenshot shows how it looks aliased with acceleration disabled, with the stroke missing in certain places on very light fonts.

However, when hardware acceleration is enabled, if I open very large images or lots of inline images at a time, the browser window will flash white, all tabs will lose their favicons, and the browser must be restarted. For this reason I'm looking to keep hardware acceleration disabled, but use it (or its method) for rendering fonts only, if such a thing is possible. Alternatively I'd like a fix for hardware acceleration causing such behavior, although that seems more difficult.

Cleartype and font smoothing are both on systemwide. Disabling any of them makes the fonts even worse.

Thanks in advance.

Actually, I fixed the issue. Setting gfx.direct2d.force-enabled to true was all it took.
