"poll=t" where "t" is a floating point time.

Setting the option "level2" will limit the search
for non-default visual windows to two levels from the
root window. Do this on slow machines where you know
the window manager only imposes one extra window between
the app window and the root window.
Also for very slow machines use "cachewin=t"
where t is a floating point amount of time to cache
XGetWindowAttributes results. E.g. cachewin=5.0.
This may lead to the windows being unnoticed for this
amount of time when deiconifying, painting errors, etc.
Debugging for this mode can be enabled by setting
