Description Todd Showalter 2010-03-30 23:14:02 UTC

Version:            (using KDE 4.4.1)
Compiler:           gcc --version gcc (Gentoo 4.3.4 p1.0, pie-10.1.5) 4.3.4 
OS:                Linux
Installed from:    Gentoo Packages

When the mouse pointer is left over something in a panel for a short time, a popup window appears.  If you move the pointer to another item, the popup changes and slides to be above the new item.  This all works properly.

The problem is that if a popup has been up for something (say, application #1), and has subsequently timed out and disappeared, and then you bring up a popup for another thing (say, application #4), the popup appears at the old location and warps to the new location, leaving behind a hole in the window.

I'm not running a compositing window manager.  It definitely does this to kterm and emacs, amongst other things.

It's a little finicky to reproduce; if the items are right next to each other on the panel it doesn't always happen, and it doesn't happen unless the popup disappears at one location before you invoke it at another.  It definitely happens, though.

If I can figure out how to attach a screenshot, I will.

This is clearly a Xorg bug, I was able to write a xlib-only testcas (as I was asked for), but then nothing happend.
