cog flickering and not HW accelerated on NXP iMX8M-Plus

[escherstair]

I have a SoM from Toradex, with NXP iMX8M-Plus.
The OS is TorizonOS (based on kernel 5.15.52) with some pre-built containers

SoC is: 'i.MX8MP'
SoC has GPU: true
SoC has DPU: false
g2d implementation: viv
Removing previously created '.X*-lock' entries under /tmp before starting Weston. Pass 'IGNORE_X_LOCKS=1' environment variable to Weston container to disable this behavior.

The containers are:
torizon/cog:3.2.0
and
torizon/weston-vivante:3.3.0
I use

torizon@649aeaf0fbbc:/$ cog --version
0.16.1 (WPE WebKit 2.38.6)

and I browse to
https://webglsamples.org/fishtank/fishtank.html
whith 1 fish and no sharks.
I see that cog is flickering, and sometimes big white squares are shown over the webpage.
Moreover the performace are poor (14 FPS) and I suspect the HW acceleration is not in use (NXP told me that I should see 60 FPS on the fishtank example).
Here iks the log from cog```

(cog:1): GLib-GIO-WARNING **: 09:40:20.217: Your application does not implement g_application_activate() and has no handlers connected to the 'activate' signal. It should do one of these.

Should I specify some command line parameter to cog?

@escherstair Could you run Cog as follows to get additional logs?

G_MESSAGES_DEBUG=Cog,Cog-Core,Cog-Wayland cog --platform=wl <url>

Hi @aperezdc
here is the extended log

Do you need other info?

[escherstair]

Hi @aperezdc ,
some months have been passed.
Do you need some other info from my side to investigate whta happens with HW acceleration on cog for iMX8M-Plus?
