Changing the playback speed doesn't work at all, two other buttons work occasionally:

In this case, changing the playback speed works fine:

Similar problem when application is opened in half screen mode:

However, in slide-over mode, all buttons work fine:

The AirPlay and Sleep Timer buttons sometimes work in full screen mode, but I cannot change the playback speed, even with the stylus.
By the way, in slide-over mode (last screenshot), when the playback speed is 2x, it is also very difficult to change with the touch, only with the stylus.
