I have problem about CPU & Memory on Opera Dev 50. When I updated to 50.0.2753.0, CPU and memory is used higher more than previously version(Opera Dev latest 49 version before up to 50).
It's just open program and wait about 5-10 minutes, CPU and Memory are used high and hang or freezing. I'll tried to disable any addon and it doesn't work. I'll tried end procress by Task manager on browser(by Shift + Esc) and close any tab + running background so it doesn't work too.
I closed any tab + running background by Task Manager. See image
And this is graph of running CPU and Memory. It's very strange...
And the last one is all procress running while open Opera Dev 50.0.2753 browser.
So it's a bug? if not, how to solve this problem?
