RPI4 on Libreelec 9.1.502 (also on 9.2) subtitles cause playback to skip frame or 2

Well , it seems i found a workaround that seems to work just fine for me.

Found it under this post : LibreELEC 9.2 beta 1 video judder and stuttering.

Just add

Code

<gui>
  <algorithmdirtyregions>0</algorithmdirtyregions>
  <smartredraw>true</smartredraw>
</gui>

to your advancedsettings.xml and restart kodi.

This file i put on, /storage/.kodi/userdata?

Yeah

/storage/.kodi/userdata/advancedsettings.xml

if file does not exists create it and it should contain :

Code

<advancedsettings>
  <gui>
    <algorithmdirtyregions>0</algorithmdirtyregions>
    <smartredraw>true</smartredraw>
  </gui>
</advancedsettings>

you can verify on kodi log file that its being loaded.

Just an update if any one cares.

smartredraw is not needed in my case to fix subtitle issue , it causes weird gui issues so only the following is needed :

Code

<advancedsettings>
  <gui>
    <algorithmdirtyregions>0</algorithmdirtyregions>
  </gui>
</advancedsettings>

I have the same issue with subtitles since the beginning with my RPi4. I tried the workaround with the advancesettings file and actually it stopped the stutters when the subtitles show up.

But I noticed, that the audio starts to have little variations. I noticed it during the music parts in the movies.

Is there any update to this problems?

Actually it got better with the lattest update 9.2.6 but the subtitles stutter is still there. And with my RPi3 everything works fine.

Any other solutions?
