Description kronheim 2007-01-10 11:35:45 UTC

Running current compiz from git (`compiz --version` == 0.3.7), the following occurs:

1.  Start a compiz/gnome session and launch gnome-terminal (or anything else)
2.  Maximize gnome-terminal (e.g. by clicking the max button on the title bar)
3.  Click on the title bar of the maximized window (button 1)

Expected result: nothing much
Actual result: whatever is behind the gnome-terminal window receives the mouse
click (typically the desktop)

This happens when using any type of window decoration (including the built-in
decoration). It happens with any application window, and any mouse button. It
also happens if the window is just maximized vertically.

Version 0.3.6 did not have this bug. I earlier mentioned this problem in a
comment on Bug #9257, and incorrectly stated there that this problem only
occurred with kde-window-decorator.

Sounds like frame window used for input is not updated correctly for some
reason. It works just fine for me so I don't know exactly where to look but I'll
see if I can't figure out what could be wrong sometime soon.

You can use git-bisect to track down the commit that caused this problem. Doing
that would be very helpful.

From git-bisect:

dc5833fcb4b0c3cd2dfc0a81e7a7209a3104e40f is first bad commit

Ah. This bug is reproducible only if you turn *off* the "Maximize effect" in the
wobbly plugin.

Comment 4 David Reveman 2007-01-18 09:31:48 UTC

Should be fixed now.

Yes, I can't reproduce the bug now with the latest version.
