Excessive CPU usage while connected to an external display about animatedgif HOT 3 CLOSED

Hi Shame Sung,
I did a couple of tests with the systems I have here.

• new 27" 4K Display from LG
• old 22" Display from Samsung
• MBA from 2010
• MBA from 2015
• MBP from 2008

But I don't get any excessive CPU usage of AnimatedGif when using those systems in different possible pairings. Not even when running MBA 15 and 4K Display in a 4K resolution I got problems.

So I wondering how to reproduce the problem? What could be special with your system?
Can you tell me some details about your configuration please?

• your OSX Version
  (I stay at 10.11.3 because higher version causes the known freezing problem on my MBA 2015.
• your Mac hardware in detail (GPU chip, etc. pp.)
• your Display hardware in detail
• connection you use between Display and Mac (Thunderbold, DisplayPort, HDMI, DVI, ...)
• the used GIF (as we see in older issue especially the GIF could be a reason, maybe you create your own 4K GIF (have no clue if this is even possible)? )
• used resolution and refresh rate with problem
• the settings you set in AnimatedGif

Well hope we can catch the problem. Greetings

edit: I'm an idiot, i'm using a quartz composition screensaver instead of yours

Yea, I used them before too. One of the main reasons why I start to code my own screensaver was the high CPU usage of the quartz composition solution.
