hi Nicolas, thanks for the report.
Could you please clarify, how did you measure performance degradation?

In my case I could only enable fps counter and saw these values:

mesa-18.1.5 (system) - 43.* FPS
mesa-19.0.0 (from git, release) - 36.* FPS
video in use -
http://cdn.clipcanvas.com/sample/clipcanvas_14348_ProResHQ_720p50.mov

My monitor is Dell (system resolution 1920x1080)

To enable fps counter I removed (--no-config) and in the mpv.conf file added
this:
>osd-msg1="FPS: ${estimated-display-fps}"

path for config file:
>~/.config/mpv/mpv.conf

To summarize, this fps drop could be determined as degradation I think, but I
want to clarify what did you mean.

oh, btw, mpv version is:
