[Bug 1390892] [NEW] Windows stacking (foreground/background) gets completely screwed up

 

Public bug reported:

I have reported several issues (none of which got the slightest
attention, by the way) but I now realize they ALWAYS happen all
together, so they are most surely just consequences of one same issue.

At random times it happens that the front/back or in-front/behind relation between windows becomes badly screwed up in several ways:
1 - windows are on top of Launcher while Launcher should always be the topmost
1b - even the context menu of Launcher icons that appear by right-clicking on them turns out to be behind maximized windows (or non maximized windows)
2 - the window-switching selector that shows up when you hit Alt+Tab is on the background (hence invisible most of the time unless you minimize all windows or show desktop)
3 - Fullscreen content from any browser, such as for example fullscreen of video or flash content, goes fullscreen on the background instead of on the foreground; even clicking on it (if some portion of it is visible behind the foremost windows) doesn't bring to the foreground, the only workaround (which was difficult to figure out) being: ctrl+super+d and then click on the browser launcher icon.

Sometimes (3) is slightly different, in that the fullscreen content
stays on top of everything except Launcher.

All of this is very annoying and this issue has been around for a very
long time, certainly more than a year (i.e. two releases) if not
forever. This cripples the usability of the whole system to the point
that one is forced to restart, which is painful. This should be high
priority.
