I could throttle/unthrottle the fps on the original app with or without title and everything worked for that app as expected.
Removing the cache did not help with the other apps at first.
To get the other apps to work as expected, I set the title in one app. started app (this showed no throttling), shutdown app, removed the title and now everything is fine. No interference from original app no matter what I do with it. Cache must of been screwed up.
That is plain weird.
