I have the same menu rendering problem as well.
Current specs: Sony VAIO VGN-FZ290
Win7 x64 w/ SP1
Nvidia GeForce 8400M GT Driver Ver: 257.41 (this is modified 3rd party driver, seeing that Sony doesn't provide a 64bit video driver and the driver from Nvidia will not install)
FF 18.0.2 w/ NoScript 2.6.4.4
For me, I found that enabling "Use hardware acceleration when available" under Tools>Options>Advanced>General tab, made the menu rendering issue go away, but it created a new problem. While browsing using FF, my computer would randomly freeze. I would have to hold down the power button to turn it off and start it back up. The video driver version I was using at the time was 306.97. I just recently installed ver 257.41. I will enable hardware acceleration and see if my computer freezes. I will also test out FF 18.0.2 with no addons and hardware acceleration enabled to see if it's FF causing my computer to freeze.
I don't remember seeing this issue when I used FF 17. Hardware acceleration was disabled on FF17. Right now I'm running FF 18.0.2 w/ Noscript and with "hardware acceleration" disabled. So far no freezes, but I do have the NoScript menu rendering problem.
