I guess I will have to give Chrome a chance then.
Thank you all very much for the informations, I wasn't aware of the direct2D implementation.
Reading the forum link that ROJOhound provided it seems that there is still hope. Azure will make use of Skia as a replacement of Cairo for all software rendering and OpenGL. Skia is already activated for the Mac versions, and a bug comment from today looks promising. They tested a build for Windows successfully and it seems it will be implemented as another option in the preferences to manually enable Skia, so that people having Direct2D will also be able to alternatively use Skia.
Thanks once again, I wouldn't have learned about it without your answers tulamide2011-11-08 18:08:37
