Arch Linux with KDE Plasma Desktop (Wayland session)
AUR (mpv-git)
I don't known which version of mpv introduced the problem
KWin 6.0.4 (without using scaling)
Intel Graphics HD 4600 / libva-intel-driver 4.2.1
My configuration:
vo=gpu-next
hwdec=vaapi
gpu-api=opengl
vf=vavpp:deint=motion-compensated:interlaced-only=yes (put in a separate profile for "video-frame-info/interlaced" == true).
I sometimes watch various sports broadcasts. Often it's 1080i50 and I don't notice any issues with frame drops or jerks. Everything looks fine when I turn on a 720p50 broadcast and watch in a window. But I immediately see a slideshow when I expand the window to full screen mode. I can also see frame skipping in the log. It is logical to assume that the problem is related to scaling. I specified explicitly scale=bilinear and the frame skipping almost stopped. But with all other better scaling options everything works terribly. When using vo=gpu with default scaling there is also frame drops but not as bad.
I installed the Vulkan driver today and specified gpu-api=vulkan. With these parameters everything works as expected. Maybe the problem is related to OpenGL in Wayland or specifically KDE.
