Subtitle stutter 8.90.3

[Sholander]

@startv

I typed these code in advancedsettings.xml

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

reboot ,no work.
and the CPU’s temperature raise high.

This is my advancedsettings.xml:

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

First line stops stutter on files like this sample
Second line eliminates stutter on files like this sample, which first line does not eliminate.

So I keep both lines and CPU temp does not rise at all.
