A question about text scrolling

Description

I created the interface in the video below,and the label on the middle line is scrolled.But when all four of the middle labels scroll, the program gets stuck inside lv_task_handler() foa a long time and I can’t switch between screens during that time.

What MCU/Processor/Board and compiler are you using?

NXP IMXRT 1052

What LVGL version are you using?

v7.7.1

What do you want to achieve?

What have you tried so far?

I found that there are only two labels that scroll without getting stuck in that function.I don’t know how to upload videos,so I compressed the video.

Code to reproduce

Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.

The code block(s) should be formatted like:

/*You code here*/

Screenshot and/or video

If possible, add screenshots and/or videos about the current state.

  1. Please try updating to the release/v7 branch on GitHub and check if the issue is resolved. 7.7 is quite old and missing quite a few bugfixes.
  2. Please send a code snippet that can be used to reproduce the issue.
