Trust me there is and it was jerky just the video doesn't show it up well that's why I was reluctant to do it.
Honestly from your video I can't see if there really is any scrolling problems, it seems pretty smooth from the video at least.
Despite Adreno 305 not being a high end GPU it does power a lot of 720p displays pretty smoothly.
Take for example Galaxy Grand 2 or HTC Desire 816, these phones are run by Adreno 305 at 720p resolution.
Yeah I guess I agree it's as almost as if when you scroll the screen is shaking,wobbling. I have 4.11gb internal memory left,only two downloaded apps running on the background What's App and 6Tag. I don't want to block What's App as I won't get messages come through. Any apps I am using I don't have tons running at the same time I make sure I close them. As I say all else is fast and smooth but I want to know why it jerks when in Games menu which is Microsoft's own software and also when tilting from portrait to landscape in gallery it jerks again. So is it app related or not?? Cos the phones own internal software and apps kike Games and Gallery lag is not right
Both of those background tasks run for a few seconds every half hour, so they aren't really "running" in the background at all. Deactivating them makes no difference. Internal storage space is also completely irrelevant.
Why do you think my explanation doesn't equally apply to the games app and to the screen reorientation animation? I think it explains both of those just as it explains everything else you are seeing.
My guess right now would be that the GPU can't scroll those images across the 720p screen at 30 frames per second, causing it to occasionally drop a frame, which leads to the stuttering you are seeing. Without source code however, none of us can really be sure. All we can really do is guess.
Just worked out what the problem is it's the app itself. If you press the 3 dots in the bottom right hand corner then select "open in browser" it will display this page in a different format and scrolls perfectly
