I upgraded from google-chrome-stable_40.0.2214.95-1_amd64 to google-chrome-stable_41.0.2272.76-1_amd64 (automatic update on Ubuntu MATE 14.04 64 bit) and the mouse text selection stopped working and the cursor icons did not change when hovering over links in the updated browser, also got an annoying 'Enter you password to unlock login keyring' prompt when Chrome started.
To eliminate the distro from the mix I also upgraded Google Chrome on Xubuntu 14.04 64-bit from Google Chrome 39.0.2171.95-1 to 41.0.2272.76-1 and ran into the same problem.
I tried reinstalling the browser:
sudo apt-get purge google-chrome-stable rm -rf ~/.config/google-chrome wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb sudo dpkg -i google-chrome-stable_current_amd64.deb
But the problem still persisted so I downgraded back to the previous version, this worked, the problems dishappeared:
sudo apt-get purge google-chrome-stable rm -rf ~/.config/google-chrome sudo dpkg -i google-chrome-stable_40.0.2214.95-1_amd64.deb
Older versions of Google Chrome can be downloaded from http://mirror.pcbeta.com/google/chrome/deb/pool/main/g/google-chrome-stable/
