Windows Player crashes, possible memory leak #356
Description
Our Windows Players are crashing in an Interval of about 15-20 Minutes.
This seems to be undeterministic and not a direct layout error, because the screen is just showing two layouts with a cumulated duration of under 2 minutes. So the player shows the layout correctly X times, but after some time it crashes.
The Layouts are just showing a background image and a logo image (both not bigger than Full HD resolution), the second layout is a Dataset Ticker which actually shows a "No Data" Message.

[and so on ... ]
Is it possible that this is a memory leak in a web view?
Is there any further information needed to investigate this?
