According to the leaflet, different results should be expected. Indeed, in everyday life, the framerate of the interface fluctuates: 27fps-60fps. (Beelink GT1 Ultimate)
But these new parameters have not changed anything. But the subtitle problem is solved, which is not bad!
HOW-TO:Modify dirty regions - Official Kodi Wiki
0 Off The entire viewport is always rendered.1UnionAll dirty regions are grouped into the smallest possible rectangle. This is typically the fastest mode for slower GPUs due to only making one pass.
2 Cost reductionEach dirty region is presented separately, in as many passes as there are regions.
3 Whole ScreenThe entire screen is rendered if there are any dirty regions. This, combined with nofliptimeout is a safe default for drivers that clear buffer contents (manifests as blinking or vibrating images). Default
It works, the subtitle problem seems to have disappeared. Thank you very much.
On the other hand, contrary to what was indicated, I did not note any change in the general display of the interface.
No change for me. I tested with :
<advancedsettings>
<gui>
<algorithmdirtyregions> 0 </ algorithmdirtyregions>
<nofliptimeout> 0 </ nofliptimeout>
</ gui>
</ advancedsettings>
And :
<advancedsettings>
<gui>
<algorithmdirtyregions> 0 </ algorithmdirtyregions>
<nofliptimeout> 100 </ nofliptimeout>
</ gui>
</ advancedsettings>
Idea ?
Je viens d'essayer la même manipulation avec 90.5 et ça marche. Donc, ce 90.6 est faux / buggy. Pitié ! Je vais attendre 9.07. 
Good Sunday !
Or maybe you don't have 2gig ram. You may have one with facke ram, so you could try the 1gig tree.
No, the beelink GT1 has 2GB.
Too bad, I give up.

After burning the new img.gz file to the sd card. There should be a folder on the sd card named devicetrees.
Delete the dtb.img on the root folder of the sd card, and copy the right dtb file from devicetrees to the root folder and rename it dtb.img
see if this works.
Thanks ! But, Always the same...

Just did a clean install on a Nexbox A95X. And every thing works just fine
In my opinion, there is a bug with the Amlogic S912.
Et vous avez renommé ce fichier en "dtb.img"?
Paul
Yes.
I used : "LibreELEC-S912.arm-8.90.6.img.gz" ; With : "LibreELEC.USB-SD.Creator.Win32" ; With "gxm_q200_2g.dtb"
Read first post in:
Thank you very much,
I tried with "gxm_q200_2g.dtb" and "gxm_q201_2g.dtb", but, same problem.
I followed "if booting from SD/USB, simply connect SD/USB to your computer, download a proper device tree, rename it to dtb.img and place on SD/USB"
For this release you need to update the dtb file.
Thanks ! But, How to do ?
Use stable version 8.2
All 8.9 versions are only for early bird testings
On this version, I have some bugs. For example, I have the image that shifts regularly a few pixels. The clock comes out of the screen randomly.
Hello, This version does not work. Black image / No Signal after the "LibreELEC" logo 
Idea?

I've only tested it for a bit, but the two things I really noticed with the 8.90.4 & 5 releases was that the "subtitle" menu was missing and the crash after you watched a movie.
Both problems fixed with this release.
If there's anything else I should test please let me know.
For the S912 chip, when is it planned ? please
Hello !
I take this opportunity to point out something strange, which I see on all versions of Kodi. I think the quality of the pockets is low. If I compare the rendering of wallets directly on the TMBD site from my PC, some are beautiful. But on Kodi, they are degraded. Definition / aliasing and colorimetry. However, the display under Kodi is 3.840 x 2.160. I also tried to change the 4:4:4, 10-bit color gamut or 4:4:2 8bits. But never is the rendering faithful to the original covers. Kodi apply a downgrade for more fluidity ?
In contrast, on PS4, the pockets are beautiful, as in the OS PS4, as Netflix for example. (Same TV settings as Kodi)
(TV OLED UHD 2017)
PS : Désolé pour mon anglais de mauvaise qualité...
J'en profite pour signaler quelque chose d'étrange, que je constate sur toutes les versions de Kodi. Je trouve que la qualité des pochettes est basse. Si je compare au rendu des pochettes directement sur le site TMBD depuis mon PC, certaines sont magnifiques. Mais sur Kodi, elles sont dégradées. Définition/aliasing et colorimétrie. Pourtant, l'affichage sous Kodi est bien 3.840 x 2.160. J'ai aussi essayé de modifier la gamme colorimétrique 10 bits 4:4:4 , 8 bits, etc. Mais jamais le rendu est fidèle aux pochettes originales. Kodi applique t-il un downgrade pour plus de fluidité ?
À contrario, sur PS4, les pochettes sont magnifiques, autant dans l'OS PS4, que Netflix par exemple. (Même réglages TV que Kodi)
