Unfortunately, this has NOT been fixed.
Windows and Mac OS users have been enjoying the fact that most applications on their OS have been saving window position ever since the 1990s. But with Linux? Things open in the upper-left, the lower-left, random sizes, etc.
You can try to reduce the craziness of that design decision with a partial work-around, using CompizConfig.
Either search for it in the Ubuntu Software Center, or type this command:
sudo apt-get install compizconfig-settings-manager
Once CompizConfig is installed, you can find it here:
System -> Preferences -> CompizConfig Settings Manager
Go to Window Management, Place Windows, and set “Placement Mode” to Centered.
Yeah, it doesn’t really fix the issue, but at least windows will open in a more convenient and less random location.
If you want this solved, you can try voting up the issue:
