CPU ressource leak ?

[jvcleave]

Weird - I am assuming on a Mac?

[martialgallorini]

yes on a macbook pro 15" late 2013

i will try under linux

[martialgallorini]

less effect under Ubuntu 14.04.3 but still...

also, same problem with the provided example.

[jvcleave]

@martialgallorini I created a test branch for this. The CPU use certainly is reduced when minimized but I am unsure of the implication on any background tasks (i.e. OSC, image processing, etc)

hey. I gave it a shot.
It is a bit better but issue persists.

As i said, when app is in the front, it uses much less CPU.

ofApp in front and Chrome in the back :

The code is only concerned when the app is minimized. GLFW_FOCUSED (as opposed to GLFW_ICONIFIED ) may work better for background

[martialgallorini]

Yes i see. This sure is better.
But this doesn't solve the problem...

Do you think this is related to the OS ?

[jvcleave]

It may partially be related to the OS. Also depends if OF has anything to assist with dealing with app focus in place.

Why doesn't it solve the problem?
