vlc will only sometimes show video with nvidia drivers 515 (and 510) following update to 22.10

[Ian]

Typically.. the first video will play, but subsequent ones show a blank black screen although the audio is heard.

Restarting vlc will usually allow you to see the video, but again, only for the first one.

The attached extract from .xsessions-errors is when trying with the 510 drivers, but the same thing happens with 515.

.. and here is the .xsession-errors when trying with the 515 drivers.

Also happens with the nouveau drivers, so not just the nvidia-graphics ones

[Ian (superian)]

Also happens if hardware acceleration of video playback is disabled.

Status changed to 'Confirmed' because the bug affects multiple users.

In my case:

* When the first video is playing (not finished yet), you can drag-and-drop another video and this new video will start playing normally.
* When the first video completes and you drag-and-drop another video, a black window (with a white portion) will be displayed. The only solution is to close the VLC application and restart it.

So, it seems that when the first video completes normally some resource is freed and this resource is not available for the next video to be displayed.
