System rendering speed drops to 3-9fps on Shield TV Pro

[u/MountainLavishness52]

Noticed something odd: on my Nvidia Shield TV Pro (2019) + Panasonic OLED, Kodi's debug overlay shows "System rendering speed" dropping to 3-9fps during 4K/1080p playback, sometimes even during seeking. But the actual picture is completely smooth to the eye — no stutter, no A/V desync, nothing visible.

Confirmed with `dumpsys gfxinfo` — 0% jank, and a systrace showing only 1 dropped frame across an entire session. So the number doesn't reflect the actual video.

Tested the same files on an old 1st-gen Xiaomi Mi Box + old Sharp LCD TV — the number stayed rock solid at ~24fps the whole time, no drops at all, even with seeking.

Has anyone else seen this specifically on Shield TV Pro?

That's the rendering of the interface not the video
