Hi folks,
some of us over at the rox-users list have been seeing a rapid increase  
in system load when mousing over the rox panel while in openbox3. This  
seems to be ob3-only related..

I know Ben and the rest of the developers don't really use rox too  
much, but I'm hoping someone will take the time to resolve this issue  
for the sake of standards compliance.

Below is (part of) the thread from rox-users, describing the problem in

Here rox is at 40%, X is at ~20% and ob3 is at 10% system load.
There's something funky about the tooltips. Since some of us are using
ob3 with no problems, I tried looking at the rox configuration to see
if any changes might eliminate the problem, but nothing came up.

I tried some more things. Here's what I found out: When I rollover an
icon no tooltips come up, and the system load increases dramatically.
Sometimes I will even see a flickering tooltip, as if it were hiding
and unhiding a hundred times a second. Now, if I click once on the
panel (sorta like raising it), tooltips work like expected and there is
no massive cpu hogging.

I'm preparing this for posting on the ob list, but just another  
question: what focus models do you use? I use focus-follows-mouse with  
raise only on titlebar click. This, or some other openbox configuration  
could be causing the problem.

Anyone have anything else to add?
