On my side, i don’t know why but it’s not working. I tried also to add the Smartdraw line.
On the debug after opening advancedsetting.xml, there is the warning “CSettingsManager: missing version attribute”. Maybe I did something wrong when i add the xml file.
On my side I would like to add that I’m also experiencing micro stuttering when watching any kind of content (h264, h265) on my Odroid-C2 with CoreELEC latest 8.99.2 build. once I have installed CE on the box I did customization manually so there are no leftovers dragged from .kszaq’s release (https://kszaq.libreelec.tv/s905/8.2/8.2.3.1/) that I use previously. And the most important information is that in kszaq’s build there are no micro stuttering at all, just zero, null.
I have all recommended settings:
no whitelisted resolutions, GUI resolution set to 1920x1080p / 50 Hz, Adjust display refresh rate set to “on start / stop”, Sync playback to display is “Off”
in advancedsettings.xml added section: algorithmdirtyregions 0 algorithmdirtyregions
and still while watching a movie time to time (once per every around 15 - 20 minutes) there is micro stuttering noticeable.
I have collected kodi.log with “FFmpeg libraries”, “Audio component”, “Video component”, “audio/video timing information”, “Database component” enabled and I see the following entries when micro stuttering occurred:

No subtitles muxed nor in external srt file but to be honest micro stuttering is much rarely happening since I have added algorithmdirtyregions 0 algorithmdirtyregions section.
File created is almost 30 MB so if you need whole log let me know how I can deliver it to you.
I’m looking forward to be helpful for you guys in troubleshooting this micro stuttering issue.
Still trying to get more information.
These are the kodi.log lines when micro stuttering occurred and was noticeable visible at 11:22:02, 11:26:41 and 11:27:01:
I solved my issue. I fact the advancedsetting file (dirty region) is working. the video stutter only the first time subtitles appears. After that there is no more stutter.
Hope that this reply will help people who have the same issue.
Thanks to the CoreElec team. You gave me the solution before and I didn’t realise that the stutter occure only one time
