Is glesv2 a mandatory dependency on Raspberry Pi ???

[WebReflection]

I've just tried again cog and I always get a Display EGL failure at bootstrap, but only when running it via Weston on a Raspberry Pi. The whole thing looks half accelerated too, where I have little FPS for the classic jellyfish demo while I used to be able to go at nearly stable 60FPS before.

The only thing I am not using though is the explicit cairo-glesv2 version of the library, but I thought with latest mesa and VideoCore mainstream support that wouldn't be needed ... am I wrong in assuming this?

Also, I have cairo-glesv3 too available, but I haven't seen that mentioned in README ... is GLES v3 any better or nothing really works or changes if I use that instead? (I could try, but hearing from you would be a way better outcome).

Thank you!

FYI even using those glesv2 or glesv3 solutions I can't avoid the warning about the Display #614

That warning can be ignored, things usually work despite of it.

OK, I can ignore the warning, but it used to go around 50FPS on a Pi Zero 2W https://www.youtube.com/watch?v=kkqheU0PnjI

now on a Pi4 it never goes faster than 18FPS, it doesn't even matter if I am running at 720p or 1080p, it's basically "as slow" as Firefox with WebGL but it used to be much faster.

I've seen many things changed here and there:

• the weston --socket=wpe does nothing now
• the WAYLAND_DISPLAY=wpe breaks, likely due previous point
• before I used xorg that was launching weston with xwayland and then cog ... now I am just using weston and cog (no startx, no xorg-server, no xwayland) and while I have no errors whatsoever, and the HW acceleration seems to work, it's really underwhelming compared to 1 year ago

Is there anyone able to run this demo with WPEWebKit and on a Raspberry Pi at more than 18FPS?

Thank you! I feel like I might be missing something really silly or simple, but from a whole updated stack, including better Mesa support for VC4, I can't believe I am incapable of going as fast as I used to when things were a bit sketchy on all fronts!

Have you checked which CPU governor is using your RPi?
Please execute this command:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
If it says powersave then that is your issue. You have to change it to ondemand or performance

[WebReflection]

I've used cpupower with performance governor and literally nothing changed ... I will try to see if that other command makes any difference there, thanks.

I still would like to have anyone testing that page on a Pi4 and tell me what is the FPS count so we are sure it's my issue to solve.

[WebReflection]

just checked, it says performance ... it'd be great if anyone with a Pi4 could confirm the FPS count in this demo: https://archibold.io/demo/jellyfish/
