This is especially noticeable when I've just added a new audio to the slide. I add the audio, press play on the timeline, and the playhead is frozen in place while the audio plays uncontrollably in the background. Eventually the playhead starts moving, but it's inaccurate. When the screen is frozen and the audio is playing, I have to just sit there and wait for the playhead to start moving. If I click anything before the playhead starts moving again, the program can crash or freeze.

I've noticed the timeline is pretty inaccurate in general, and I have to time my bookmarks based on LOOKING at the audio wave file instead of relying on the timeline itself. The playhead/timeline is also incredibly SLOW and I have to be super careful not to click too many times, or the play button will literally disappear while the audio plays with the playhead not even moving. Or, the first time trying to play a slide with a new audio will cause all the elements on the slide to disapear and I have to click to another slide to refresh it and start editing it again.
