Really choppy scrolling in menus

[HEPOSHEIKKI]

Scrolling between items in libraries and the front page is really choppy and the animation is slow, is anyone else having this issue or is it just me?

[IvanBernatovic]

@HEPOSHEIKKI I have the same issue but it's a bit better if I disable images in the background.

It's faster than Plex for me lol

I have this same issue with no custom css or backdrop. Scrolling through movie listings is choppy and the only device with the issue is the Samsung TV. No issues on LG TV, MacBook, iPhones, etc.

Can you please record this behavior so we can compare performance?

[kraM1tt]

I will do when I get a chance, can you post a video of your slow scrolling?

Here is the performance on my TV: https://youtu.be/4HVnE1w0kM8 Here is the performance on an emulator: https://youtu.be/hSvaC-wYwlQ

Ah that's really choppy, I assumed you meant the metadata/artwork loading in was causing choppy loading behaviour, I can confirm mine is the same as yours after just testing, sorry about the confusion.

Any idea what could be causing this?

Having the same issue with my Samsung TV, brand new build as of yesterday too... I tried the default theme + a custom theme, and don't have backgrounds. Tried to also:

• check "Disable server-provided custom CSS code"
• uncheck "enable blurred placeholder for images"
• Library page show: 25 (instead of 100)

No difference in performance, still super choppy.

Anyone know if any older versions for the TV might have better performance? Maybe worth building an older one that'd run smoother

have someone found any solution to this ? Can we turn off animations while scrolling by using Custom CSS ? I believe animations during scrolling makes the scrolling choppy.

should I delete those lines and build wgt file for samsung tv ? function useSmoothScroll() { return !!browser.tizen; } should i delete these lines ?

return false;

[dmitrylyzo]

But for now, could you please tell me what should I do to turn off animations by changing code ?

There is no other way to control smooth scrolling other than the function mentioned. 10.8 10.9 Returning false disables smooth scrolling. It is currently enabled only on Tizen.

Returning false disables smooth scrolling. It is currently enabled only on Tizen.

Thanks. It worked. Now, Jellyfin on Samsung TV is a lot faster.

I don't think people mean "choppy" but rather non-smooth, eg. traditional. I prefer traditional but perhaps this should be implemented per person or device with the user being able to adjust this via UI.

I thought I replied to this already, weird...

Well anyway, I tried this a few weeks ago (unless I hallucinated everything, my short term memory is lacking) and it ran a lot better. If this can be made default (which it should be looking at the code??) I consider this issue ready to be closed.
