I am having a strange issue with Chrome 42 (Version 42.0.2311.135 m). Running a normal instance side by side with an icognito instance, the normal instance sometimes hangs while loading an image (I've tried with svg and png). The instance gets strangely stuck in the sense that it doesn't ever try to load images again - even when I reload the page. Some WebSocket requests I have going continue to work - but never more images.
The only way to bring chrome back to normal is to close the tab and relaunch it.
The site I am debugging runs locally on IIS 8 from Visual Studio 2013 and is a C# asp.net mvc site.
Edit
I made a little screencast that shows the bug: https://www.youtube.com/watch?v=ToTFfkYw-4s&feature=youtu.be&hd=1
It turned out that most likely this is a Chromium bug that is only appearing when running an extension that modifies host headers. Requestly is my favorite. I did some discussion together with the developer of Requestly. Read here: https://github.com/blunderboy/requestly/issues/52
I ended up posting a Chromium issue here: https://code.google.com/p/chromium/issues/detail?id=490027
