If you upgraded Google Chrome to version 9.0.597.0 dev this morning and are seeing frequent crashing of the browser, you are not alone. The problem is that the latest version of Chrome has a problem with the GPU Acceleration.
Thanks to How-to-Geek there are several solutions to fix the GPU Acceleration crashes on dev channel. The one that worked for me is adding "–disable-accelerated-compositing" switch to the command line and start it again.
This problem occurs for only those users who have turned on GPU acceleration in about:flags (previously about:labs), so you might want to go there and disable "GPU Accelerated Canvas 2D" feature for the time being and then try starting the browser without the above switch.
If the command line switch does not fix your problem, you will find more solutions at the how-to-geek’s post linked above.
