Video that shows what happens exactly

SUMMARY

Moving pinned apps on icons-only task manager moves them at random. I uploaded a video in attachment to showcase this behaviour better.

STEPS TO REPRODUCE
1. Pin several apps to icons-only task manager
2. Move them around to rearrange them
3. Click on one of them and drag it to the left or right

OBSERVED RESULT

When dragging one app, sometimes it works, sometimes when moving one app the other is moving, also it an happen that when one app is moved to a new position to the left or to the right other apps around it rearrange at random.

EXPECTED RESULT

When dragged to the desired location they should be placed there and other apps around should not move.

Is it going to be introduced/backported to 5.18 series and eventually come to Kubuntu 20.04?
Comment 3 Nate Graham 2021-02-01 19:19:30 UTC
Found the actual bug report tracking it; marking as a dupe of that.

I'll look into whether it's possible to backport without regressions.
