Black transparent bar near task bar panel (bottom screen)

Hello there.
Im new on manjaro and KDE environment, lately im curious about a lil black transparent bar on the bottom of my screen (a lil bit above task bar). This black transparent bar always appear when my cursor hover around there. Am googling it and found nothing about that bar. :frowning:


It is possible that it’s a empty panel. With option “autohide”.


i literaly cant do anything on there. I cant remove it, even i cant right click on it. :grinning:

have you found a solution?
