Maximize window freezes computer for about 10 seconds

As a note : This does not always happen; i'd say about 90% of the time.

Status changed to 'Confirmed' because the bug affects multiple users.

This also happens when restoring a maximized window to its previous size.
This affects gnome-xchat, too.

.

As an added note, I agree that this appears to happen about 90% of the time when I'm connected to my laptop dock at work with 2 screens attached. But when working off the dock at home on the laptop screen only, it happens far less often, maybe only about 50% of the time. Still extremely disruptive.

Hi there,

I got the same Problem with a second screen via a docking station.

But after deleting the nvidia driver, everything went to normal (except the bad two screen expierience by the nuoveau driver)!

So until now I'm getting used to the 'maximizing break' until nvidia making this bloody driver open source or just not so bad.

Same problem on 12.04 on a Dell Vostro 1700, 2GB RAM, Intel Core2 Duo, 2Ghz.

I tried to look at system monitor when it happens but the whole system just freezes so you can't tell what's happening. Nothing in syslog or dmesg.

100% reproducible.

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner.

Ubuntu 12.04 (precise) reached end-of-life on April 28, 2017.

Do you still see a problem related to the one that you reported in a currently supported version of Ubuntu? Please let us know if you do and in which version of Ubuntu otherwise this report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
