Description

during playback the system is constantly skipping frames. every 10 seconds or so, I see one or two frames skipped. it's subtle when watchin movies but I'm noticing it.

tested also with latest "Milhouse" build #1005 (issue NOT resolved).

Intel NUC DC3217IYE with Intel Core i3-3217U & HD Graphics 4000

on v7.90.006 ALPHA all settings stock except display refresh rate is set to 50 Hz and "Adjust display refresh rate" is set to "Always".

the issue can not be reproduced on Raspberry Pi 2 running the same release of LibreELEC. the issue can not be reproduced on Intel NUC DC3217IYE running OpenELEC 6.0.3 the issue can not be reproduced if all settings are left at the factory defaults the issue can not be reproduced if the display refresh rate is set to 24 Hz and "Adjust display refresh rate" is disabled the issue can not be reproduced if "sync playback to display" is enabled the issue can be reproduced as soon as "Adjust display refresh rate" is set to "Always" the issue can be reproduced on LibreELEC (Jarvis 16.1) v7.0.2

issue exists (for me) since I first switched from OpenELEC 6.0.3 to LibreELEC (7.0.2) that's why I had a debug log from the old version...

All Intel GPUs prior to Haswell have a bug and can't do correct 23.976. You should turn on "Sync playback to display". That makes audio resampled to display speed.
