Safari does not show "border" / "border-radius" or just badly displays them.
Safari-OTHER, OS X Mountain Lion (10.8.1), Other browser haven't such problem.
Check Safari > Preferences > Advanced
Select None Selected from the Style Sheet pop up menu.
If that doesn't help, Safari > Preferences > Extensions
If there are any installed, turn that OFF, quit and relaunch Safari to test.
By standard in "Style sheet" is selected "None Selected".
I have not any installed extensions in Safari.
But thanks.
If you have the Develop menu enabled, make sure Safari 6 is selected from Develop > User Agent
Here is the same problem, but while without solution.

Ok.. check out my previous post.
In "Develop > User Agent" was selected default. I selected "Safari 6.0 - Mac".
Still does not work.
Try troubleshooting third party plugins > Unsupported third-party add-ons may cause Safari to unexpectedly quit or have performance issues
I have tried. Did not help.
