vlc creates "zombie-process" when closing while video is playing

[AllesMeins]

Since I did the upgrade to 20.04 vlc does no longer close correctly. If I close vlc while a video is still playing, the window disappears but a vlc process keeps active in my process-list. Also the little systray-icon stays. If I browse thru many videos a lot of vlc processes clutter up my system. If the video is stopped, vlc closes regularly.

Steps to reproduce:

1. Open a video with vlc
2. Close the player while the video is playing

What happens:

The vlc window vanishes, but a vlc process stays active in the background, consuming memory. If enabled the systray-icon also stays

Change the video output to XCB & it closes properly .
I set it on XCB & then revert it to automatic & WOW it now closes properly as well.

Thanks Mohammad Reza Moghaddasi. Thats work for me. The solution steps are following:

Tools -> Preferences -> Video (tab) -> Output -> XVideo output (XCB)
