There should be no problem with ths one since WMs are encouraged ("should", *sigh*) to set _NET_WM_HIDDEN for minimized windows and the major ones do.
If _NET_WM_STATE is absent it's considered 0, thus does not match HIDDEN, thus passes the check over to the ICCCM state.
The "weird" condition is when a window has HIDDEN but not inconified, just that this is what the patch uses a fix.
No apparent concerns from my side.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">When setting "Keep window thumbnails" to "Always (Breaks minimization)", kwin will keep WM_STATE to be NORMAL when a client is minimized while including _NET_WM_STATE_HIDDEN in its _NET_WM_STATE, as confirmed by ICCCM[1] and Extended Window Manager Hints[2]. However, apart from the expected result (breaks minimization: the client will continue to refresh its content) the minimized window is not shown as minimized in icontasks and pager.
These two plasma addons (and probably other addons as well) uses KWindowInfo::isMinimized to determine whether the window is minimized. However, this function threat all window that are not Iconic (WM_STATE != ICONIC) as not minimized, in contradiction to the "Extended window manager hints" which says, "Pagers and similar applications should use _NET_WM_STATE_HIDDEN instead of WM_STATE to decide whether to display a window in miniature representations of the windows on a desktop."
This patch correct this behavior and therefore correct the behavior of both pager and icontasks in this situation.
