Hello,
we have a SPA (Durandal, Knockout). Additional we use SVGs at many places.
We also have a SVG that is controlled by Javascript (color, text components, animations).
Everything works fine, until KB3093983 was delivered to our customers.
This Updates leads to some strange behaviour.
One workflow in our app is like "Open a 'tab' inside our app", "hide the main page", "show the tab", "do something", "close the tab", "show the main page".
The tab includes several of the former mentioned animated SVGs.
When it comes to the step where the tab gets closed, the CPU increases to 60% and the IE11 takes up to 1.5GB of RAM. After about 6 seconds the CPU gets back to 0-3%.
The whole process works fine in Chrome and Firefox.
When I take a look into the DEV Tools, the Memory Snapshot shows me only ~8MB for the Javascript Objects.
Does anyone have similar issues or can give me a hint how to solve this?
