Leap 15.4 + Mesa 21.2.4.
VLC and all codecs goes from Packman repo.
Problem started after upgrade from Leap 15.3 to Leap 15.4.
I see horizontal lines with enabled hardware acceleration at the edges of objects, and no such things with disabled hardware acceleration.
ILL problem is with deinterlacing settings.
Which settings are the best for picture quality?
