Screenshot of Activity Monitor
Summary:
If you display several large files in Safari/Webkit loaded from the local filing system (e.g.. file:///Users/waynestewart/Desktop/sample_1.jpg) the memory for these is not released if you load a subsequent image in the same tab/window or reread the image.
The memory is released when you close the tab/window however.
Steps to Reproduce:
1. Get a large image or pdf (note pdfs are better as you can get some really large ones!) from finder and load in Webkit
2. Drag another image or pdf into the address area so it loads
3. Repeat with more images/pfds
4. Alternatively you can just have one image/pdf and hit reload (Command R) multiple times.
5. Look at Memory usage in Activity Monitor
Expected Results:
Memory usage should be appropriate for the currently loaded image
Actual Results:
Memory usage continues to increase
Version:
OS X 10.11.5 (15F34)
Configuration:
