Probably more than one driver is affected. But I did spend several hours troubleshooting it on an affected system and so far it does seem like a driver bug: the driver is blending the last line of visible pixels with the first line of pixels outside the visible area. All zeroes corresponds to dark green in YUV colours space. Now, I´m not flawless, but with no further arguments, I consider this a driver bug. Considering how bad of a reputation XVideo has accumulated with GPU driver developers, this is not even surprising. VLC 3.0 is intended to switch to default to OpenGL (GLX) rather than XVideo. Debian might consider doing the same in their VLC package. This should work around the bug and would also improve scaling of subpictures. But of course, it would expose other potential GPU driver bugs. -- Rémi Denis-Courmont http://www.remlab.net/ -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
