Unity's top panel sometimes covers windows headers right after launching them (windows position problem)

[Tamir]

Unity's top panel sometimes covers windows headers right after launching them (windows position problem). It is not possible to control (close, minimize, maximize) window without druging it down by pressing Alt+Left Mouse Button.

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

[Alberto Salvia Novella (es20490446e)]

It renders essential functionality of the package (or a dependent one) broken.

[Stephen M. Webb (bregma)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we cannot work on this bug because your description didn't include enough information.

From some of the words that appear in in the description it sounds like perhaps the Unity Panel is not appearing in your system. Are other Unity components (Launcher, Dash) appearing? Are window controls (close button, etc) present?

What commands did you use to "reset compiz" and what results did you expect?

[Tamir (sugip)]

Added a description. The problem with hiding caps windows over the top panel appears if the change /turn off the effects of Compiz. When you try to reset effects on a standard or off, you can get disables plugin Unity (a system without launcher, the top panel, hotkeys).

[Tamir (sugip)]

On a 64 bit OS similar situation

[IV (djashlar)]

confirm bug on trusty x64 . If the window Libre office is not in full-screen mode, the header of the browser window closes top panel unity.

[Tamir (sugip)]

Attached a screenshot of an open window LibreOffice, the cap of which is blocked by the header is open to full screen FireFox
