Desktop PWA on Chrome/Linux consumes 100% CPU

I’m developing an app as PWA. Until now, I used ionic serve on my local machine that works very fine. Also, when I use the “Open fullscreen” link I can test the desktop version without any problems.

Now, I installed the PWA on my server. When I open it on my Android phone with Chrome everything is fine. But when I open it on my desktop Chrome it takes 100% CPU after a few clicks. Then the app is no longer usable.

This does not occur when I open the app with Firefox.

Did anyone else had this behavior? Any ideas about a solution?
