In my new MacBook Pro I found some little bug - Safari render web elements with rounded corners with some graphical glitch – sharped doubled pixels. Not important for ordinary users, but very annoying for web developer.

After sending feedback on Apple website I realise that I need to do something more about that. I write an email to Tim Cook and few days later I received call from Apple. They ask me: "Is it you wrote a letter to Tim Cook?", I said "Yes" and they start asking me about this graphical glitch. That btw appears only in Safari 6 on Mountain Lion and Macs with Intel Graphic HD 4000.

I'm still impressed that Tim ask this people to call me and that CEO of this great company care about all customers and how all huge Apple team trying to help. Thank you Tim so much for that, thank you !

Update: In latest update Safari 6.0.3 this glitch is fixed!
Thank you, Apple!
