Created attachment 285542 [details] 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: 16GB RAM System Ram
Does this reproduce for you with Safari Technology Preview?
Yes, the problem exists in Safari, webkit and Safari technology preview. It also exists in an embedded web area that is included in the 4D database (www.4d.com) which is how we discovered it.
