Dialog windows shift when they resize themselves

[Jay S]

Binary package hint: compiz

I've noticed this behavior in Firefox and Songbird, though it may happen elsewhere.

Dialog boxes that resize themselves upon button clicks shift a little bit down and to the right when they do. To reproduce this, in Firefox with several open tabs, click "Bookmarks," "Bookmark All Tabs," then click the down-arrow next to the folder name.

Replacing Compiz with Metacity eliminates this problem. It also doesn't seem to be a problem with the "Place Windows" plugin, as disabling that has no effect.

In Songbird this can be observed when adding or removing criteria from Smart Playlists.

Ubuntu 9.04 Jaunty Jackalope 32-bit
Compiz 0.8.2-0ubuntu8.1
Firefox 3.5 rc3
Songbird 1.1.2, Build 1042

I have similar issues with emacs popup windows. Each time the pop back up they have moved a bit to the left and down. Thsi doesn't happen under metacity. As best I can tell, this is somehow related to the fact that compiz doesn't reparent windows to handle decoration. I think the amount of shift is equal to the decoration around the window. Just a theory.

These apps assume a reparenting window manager and thus do the wrong thing when compiz is enabled. The apps need to be fixed. There was a fixed applied to GTK+ for this bug but the apps you mention most likely do not benefit from it since they do things their own way.
