Sometimes css3 transforms can have bad interactions with anti-aliasing. Can you post your css? Seems to me that ‘optimizeSpeed’ is more like a bandaid than anything else.
weegillis is correct. Even though IE seems to have the most difficult problems understanding standardized CSS , it also seems to render text rather well (which isn’t worth how much IE sucks)
Aside from his solution, the only other way would be using an image (which could cause a slowing of site speed if you’re using this feature a lot)
Hi I cannot really post the CSS because it is generated by jQuery and it is pretty complicated ;P Also cannot show you an example because it is top secret
Looks like FF10 has some problems with CSS3 Transforms:http://audiojungle.net/forums/thread/soundcloud-iframe-bug/58954
It’s bizarre because other CSS3 3D Transforms in Firefox 10 work but combined with something in the SoundCloud iframe is causing the problem. (I hate to say it but I think there might be a hardware acceleration conflict with Flash )
