Download ahead causes page loading stutters on downloaded chapters.

CaidenBlock commented 4 months ago

Steps to reproduce

Enable download ahead

Download 2 consecutive chapters of any long strip that has a decent page count (count only makes it more noticeable)

Scroll between pages.

Expected behavior

Downloading new chapters in background shouldn't cause page loading stutters (like in 2.15.0)

Actual behavior

Stutters when scrolling between pages of already downloaded chapters

Crash logs

No response

Neko version

2.16.2

Android version

14

Device

Google Pixel 7 Pro

Other details

Repeatable across a fresh install on a Galaxy S22 (also A14), only changes from default are split pages (to make it more noticeable), and download ahead (set to 5)

Neither device does this with the same settings (as far as I can tell) on 2.15.0

I have a feeling this is caused by upstream, but I don't currently use Mihon and didn't see this reported there. ¯⁠\⁠⁠(⁠ツ⁠)⁠⁠/⁠¯

edit : did some testing in Mihon and did not experience this issue

Less noticeable in the clip I had chosen, but it stutters at the same time the page number on bottom changes, scrolling either up or down.

Here's an example where I scroll less wildly.

Expected (2.15.0) behavior:
