I'm not sure if this is the only time this happens, but after running xlock, a
particular dockapp has black squares in it (see screenshot). This happens every
time, but the precise corruption pattern differs from time to time. Seemingly
only that dockapp is affected, although I've seen it happen elsewhere in the
past (but I would just eventually notice it, whereas here it's 100%
reproducible). I'm using plain windowmaker-0.92, no funny compositor stuff
going on. Dragging a window over the dockapp makes it redraw properly. The
dockapp is wmauda-0.9.
In case it matters, I'm using xlockmore-5.43. The screen is black when it asks
for the password.</pre>
