Wait, I thought they were using Chromium for rendering. Are you saying that chromium uses OpenGL or that they aren't using chromium? And why would OpenGL be the cause of shitty font rendering? OpenGL handles points and shaders, not fonts - that's the job of something like freetype.
If you're talking about Windows, then maybe it will improve once this issue is fixed: https://code.google.com/p/chromium/issues/detail?id=137692
The font rendering is shitty, tough, but that's probably expected when using OpenGL.
