Why does the video jump when scrolling in JW Library?

The issue of video jumping or lagging while scrolling in the JW Library app can stem from several factors related to hardware, app settings, or codec issues. Here are some possible reasons and insights into the problem:

1. Video Codec Performance:
Some users have noted that the video codec can cause performance problems when the CPU or GPU usage spikes up to 100% during playback. This can lead to skipping or jumping videos. Monitoring the Task Manager for CPU or GPU usage can help diagnose this issue - learn more .

2. Settings for Second Display:
The "Play videos on second display" feature may interfere with video playback, especially when interacting with the touch screen. Disabling this feature can improve performance and reduce jumping - learn more .
