When I minimise Chromium back into the launcher three things occur
  • The window stutters as it minimises, and it takes a lot longer to close than any other application
  • For approx 1 minute after it has minimised the Global Menu for Chromium flashes on and off
  • Once minimised the system locks up for approx a further minute. I cannot open or use apps and all menus are unresponsive.

I am aware that there were issues with slow minimising windows in 12.10, and I have amended Dconf Settings to solve this, and all other apps work fine

Not sure where to go with this query - any advice greatly appreciated.
