How can I solve the Chrome performance problems on Ubuntu Gnome 15.04?

I installed Google Chrome on Ubuntu Gnome 15.04 from http://www.google.com/chrome/ , without an existing browser profile in ~/.config. Syptoms:

Typing in a form textfield on a web site is stuttering and lagging one second behind the keystroke.
Clicking a button has a delay of 1 second before the browser shows the click down.

I also installed Chromium from the Ubuntu repositories, same problem. I assume some rendering library is slow or maybe the graphics driver?

$ lspci -nn | grep VGA
00:02.0 VGA compatible controller [0300]:
Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02)

Video driver is i915.

Firefox performs normal on this computer with no noticeable delay, so this seems Chrome-specific.

This was a bug in Ubuntu 14.10. Chromium was slow in graphics rendring. There is a workaround

Run following command in terminal sudo xdiagnose and disable bootloader graphics, VESA framebuffer driver and PAT.
