Javascript bugs in Safari 6 on Mountain Lion

Since I've upgraded to Safari 6 on Mountain Lion I'm having several problems that seem to be javascript-related. On many sites, for no apparent reason, interface elements will stop receiving click events. For example, checkboxes and buttons don't respond when clicked. Links don't respond if they have a "click" handler but they will work if they are plain links with an href. If I try to reload the page it stalls, as if the server is not responding. I have to relaunch safari in order for the site to load and it will inevitably happen again... just not sure when.

Other points:

1. I've seen this problem on several different sites across many domains, it's not limited to a particular site.

2. There are no javascript errors (that I can attribute to this problem) and javascript is enabled (of course).

3. For all the sites that I've experienced this problem I've loaded the same site in chrome with no problems.

4. Safari was my default browser before the upgrade and I've never experienced this problem before.

5. The only extension I have is 1Password. I tried disabling it but it hasn't improved the problem.

I'm hoping that someone else is esperiencing this problem and either has a fix or can help me get Apple's attention so they will issue a fix.

Thanks!

MacBook Pro (Retina, Mid 2012), OS X Mountain Lion, Safari 6

I have noticed that some pages "load" but are blank. They do open correctly in Chrome. I have also found some pages that have overtyped text and controls (scrolling lists) that are completely messed up. There are clearly some problems with Safari 6.

I have the same problem. After a while elements is unclickable. And when I reload the page to fix it it freezes. Safari has been my primary browser for years, and it has not happened before.

JavaScript is not Java.

I'm having a lot of JavaScript related issues with Safari as well. Elements stop responding or glitch out and flash white. Reloading the page usually fixes that page in the short run, but it doesn't take long for JavaScript elements to start freaking out again. Even forms that rely on JavaScript have major issues: the text will flash white and parts of it will become obscured/hidden. It's really annoying.

Since loading Mountian Lion, I too, have had some browser problems. Most notably when backspacing to correct a word. The backspacing has been erratic and was ghosting out words as well. I've also had page rendering problems.

I went into the language and text settings to turn off the autocorrect "feature." It seems to have helped with the backspacing problem as well as some page rendering issues.

Additionally, animated GIFs freak out and are not animated correctly. Frames skip, flash white, etc.

@tonyselliot: I've had that "feature" disabled from the get go and still have enormous amounts of problems related to Safari's JavaScript runtime.

I have been running Lion and Safari 6 without issues until yesterday when every web page seemingly started to fail with javascript related issues.

I have found some relief (well, for 24 hours :-) ) by performing the following.

Reset Safari completely.

Turn off JavaScript within Safari preferences.

Reset Safari completely.

Turn on JavaScript within Safari preferences.

Now, as sure as I post this I'll start having issues again, but on the off chance it helps another until Apple corrects the root problem, I wanted to pass along.

Just tried running the sunspider javascript benchmark. Safari crawls though, getting slower and slower. It never even finished. Chrome and Firefox worked fine. (Mountain Lion)

I am certainly having this problem with Safari in Mountain Lion. Web sites that are high traffic, like eBay and facebook, are more troublsome. I am getting big white blocks that can only be fixed by reloading.

hey i have the problem similar to yours just that i have 1 more problem, this only happen when i set Google as my default search engine in Safari Preference.

I tried reset safari but no use.

Disable cache/Deleting the cache in ~/Library/Caches/com.apple.Safari/Cache.db and restart Safari only helps for awhile before the problem comes back again.

Temporary the only way i found out is to use other search engine like yahoo or bing as the default search engine to resolve this issue.
