I had a look at the preferences window, video tab. The "Output" option
was automatic.
Looking at the logs, I notice it was selecting xcb_xv (XVideo)

I manually changed it to "OpenGL GLX video output (XCB)" and the problem
goes away.

"xcb_glx"
Looking at the mpv logs as well, it appears to be using OpenGL by default:

Is there any other detail I should look for in the log?
Should the automatic setting use a different default?

Daniel

Bug#881489: playback scaled to 4k fullscreen is choppy
Package: vlc Version: 2.2.6-1~deb9u1 Trying to play a video file with a resolution 720x526, 25fps, MPEG-1/2 (problem also observed with other videos at different resolutions) With the window maximized and the option "Always Fit Window" selected, it appears to zoom to 3:1 and playback appears good. When fullscreen is selected (up to the 4k resolution of the display), I frequently see what appears to be a horizontal tear across the middle of the picture, especially when there is a lot of movement in the video. Using mpv 0.23.0-2+b2 at fullscreen with the same video I don't observe the problem. I don't have libvdpau1 installed due to problems with the frame rate[1] Hardware is Intel i3-7100U CPU @ 2.40GHz and Kaby Lake integrated graphics Intel HD Graphics 620 (Kabylake GT2) Regards, Daniel 1. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=856535 ___ pkg-multimedia-maintainers mailing list pkg-multimedia-maintainers@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/pkg-multimedia-maintainers
