opening new gmail in Opera taking up entire CPU

I switched to the new theme in gmail, launched a week ago.

When i check the processes running in the system, i get the following.
It creates multiple processes for googletalkplugin, and sucks up the entire CPU.

I tried with Chrome browsers, it works fine, and CPU runs fast enough.

What version of Opera is it ?

To check: In Opera click the "OMenu" at the top left of the browser ---> help---> about Opera ---> starting at the top of the page the version number and build will be listed

Cant reproduce any problem like this with any current version or testing versions opera

yes this is problem with last 2 builds of opera 12 next. When moving mouse or using gmail, cpu usage is high upto 50% on 3.6ghz dual core.

Same here. Opera 11.60 - using "new" gmail makes opera.exe utilize one kernel 100%.

Is there any common denominator here? I notice one AMD GPU up there, any more in this thread? I have one too and 11.60 was completely unusable for me, didn't load pages, was slower than frozen molasses, sucked up even more ram than 11.52 (which is saying something)...

its not gpu related,
new gmail is heavy on javascript and uses styling (?, dont know what technology) that is heavy on cpu in opera, Scrolling or just hovering mouse over buttons is killing cpu. how displaying a stupid popup over a button could eat 4GHz cpu ???

Gmail freezes up recently in Opera 11.60 on my Win7x64 pc, but not on my WinXPx32 laptop.

I tried deleting userjs, but made no difference.

Same here. After update from 11.52 to 11.60 gmail (and sometimes Youtube) is unusable.

Same problem comes up when my screen goes black (after 15 minutes after last mouse move) and I have gmail or Youtube opened in active tab. Hope it will be repaired soon.

Know what, even Chrome 16 uses ~50% CPU on one core just when you move your mouse over GMail window...
Needless to say, Opera uses much more...
I'd say it's not the bug in Opera itself, but inefficient use of Javascript by Google – New GMail relies heavily on "onhover" and "onscroll" events, which Opera fires at high rate, clogging your CPU...

Confirmed, 100%cpu usage with 11.60 on gmail.

Other websites seem to use alot of cpu, but not as much as gmail.
