Too many artifacts in video playback

I notice that there are too many artifacts in the video playback compared to other players such as GOM Player. At one time I had no problems with the VLC player for iOS but it is too glitchy now. Can you please fix?
Thanks so much.
P.S. I do really like your wifi sharing. That works extremely well and fast in light of the fact that Apple in their “wisdom” changed how files are uploaded to apps in their latest iTunes update. FYI: don’t update your iTunes to the latest!
