<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">The problem here is that we're caching pointers, and I'm not sure that every pointer in m_backgroundContrastForcedBefore is still valid, as there's zero bookkeeping for vanishing windows. This approach sounds rather a lot safer to me, stackingOrder() is something I can trust.</pre>

When the sliding effect is active, the background blur of the panel
would be disabled unless forced with WindowForceBackgroundContrastRole,
which is actually what we want: during sliding, the backgroundcontrast
effect would otherwise be disabled, leading to the panel and popups
flickering between contrast enabled and disabled.
With this patch, the panel keeps its coloring during desktop changes.</pre>
