Really? I see no slowdown whatsoever. What are you running?
It didn't die this last time so I must have just had a perfect storm of activity right at that moment.
Yeah it locks up Chrome for me, pressing Ctrl+w closed the tab after about 10 seconds. Chrome 20 on Ubuntu 12.04 x86_64. Core 2 Duo with Intel graphics.
It did fine for me on Chrome 20, Arch 64bit. Also a dual core, but nVidia graphics. Maybe the intel graphics drivers are being weird?
works fine on Win7 32bit + opera 12
I started zooming out and my graphics driver crashed which is quite a rare a occurrence these days.
