Hello i was wondering if someone else have those bars; they usually appear if i slowly move the mouse towards the dock or panel,which are set to auto hide. sometimes they also get stuck for a bit,or appear under the dock. ▶ Summary

KWin edges are an important plasma way to communicate a dock/panel with the kwin window manager. If you dont want their visual, you can simple disable them at: Plasma SystemSettings → Workspace Behavior → Desktop Effects → (disable) KWin Edge effect

seems the same as this issue,it’s just that my panel and dock are much smaller,so so is the Bar.
