Ever since I upgraded to Ubuntu 14.04 from 13.10, I will have windows that open with the top bar of the window obscured by the top bar of the screen. I can move the window once it is open, and then accessbut it is a minor inconvenience to do so.
I saw some historic threads that mentioned a Compiz manager to adjust this, but I didn't know if it was still the preferred way or if it was obsoleted.
I think the issue is that the window that opens is too large to be fully displayed in the screen, and before the OS preferred to put the window bar just under the top bar. I was missing more on the bottom, but I could easily access the bar to close the window. Now it seems to split the difference and put the window centered with a bit obscured at the top and the bottom. I am missing the bar at the top, and I don't see the bottom of the window either.
Edit: Posted screenshot of issue.
The best workaround I have come up with is:
compizconfig-settings-managerfrom the software center
Repeat as needed for all program causing problems and adjust
Ybased on you launcher and panel scaling. some time you have to restart for the setting to take effect.
hope this helps cheers! Whitaar
