The Shaun's solution almost works but now a new problem occurs.
When another window occludes my OpenGL window, even partially,
well, now my
animation runs at a higher speed. Too much. It is not synchronized
anymore
with the display refresh rate. My app it's supposed to run at the
display
refresh rate, so I can get the max smooth quality. So the Shaun's
solution
as it is actually, is not useful for me.
Yes, Mike. You are right, it's better to avoid bad surprises to the
users,
... but how to fix this problem?
I cannot put another application's window over my application
window. If I
do, this top application runs very very slowly. For example, I
cannot drag a
file onto my application because once I open a Finder window over
my OpenGL
application window, the Finder gets stuck. Opening a subfolder
requires 10
seconds... tipyng a text string other 10 seconds. Selecting a
string on my
XCode window requires 5 seconds about...
I cannot sell my application this way. And I invested many months
in this
project. The problem never occurred with Panther, so please let me
know how
to workaround the problem.
I would file a defect with Apple and consider contacting DTS [1] if
you want Apple to help you directly on this issue (likely get you to
any possible work around more quickly).
As I noted earlier I don't see this issue (the one you outline above)
so please outline what hardware is involved in your testing. I have a
feeling it is ATI or possibly single CPU related. Please feel free to
fire me a copy of something that you want tested on my setup here.
(again may I suggest we take this to just one list, as it is now we
have 3 separate threads taking place on thread separate mailings list
each with a different mix of messages... sounds like the quartz list
or opengl list would be best)
