This is exactly the same thing I experience on my NUC7CJYH. Turning on any sort of info overlay on the screen stops the "stutter". It doesn't happen all the time, but I'm going to try and grab a debug log today when it does.
Looks like there was someone else with the same issue that solved it with some config changes to DRI/Mesa - https://forum.kodi.tv/showthread.php?tid=299115&page=7

it looks like /etc/drirc is read-only on libreelec and i wasn't able to add the lines to the configuration. anyone know how to try this fix on /etc/drirc? 

Can you test with build #0702b: Generic and confirm it the stutter is any better/worse/no different? Don't force i915_min_freq when testing this build.

#0702b includes a commit that reverts a change added in 4.17-rc1 which aims to avoid boosting the GPU unnecessarily but which seems to have the effect of never allowing the GPU to boost at all when being used by Kodi (tested on Skylake). 

This build works perfect for me with no forced settings to the i915_min_freq. Thanks!
