Woohoo progress!
I feel like this isn’t getting the attention it deserves but it’s a really big deal for L5 and GNU/Linux mobile.

This would be absolutely stunning.
Currently Flutter apps on Librem 5 seem to be damned to use only software rendering, resulting in very improvable performance…

How do you check this and how install the app?

I observed that when running a self compiled Flutter app. Flutter does not fallback to software rendering by default and showed an error. There is an open issue here: Support software rendering fallback on Linux · Issue #151389 · flutter/flutter · GitHub
Another app example is FluffyChat, see: Installing / using fluffychat
Some suggested to use Flatseal for unchecking GPU acceleration. In my case I just added Flatpak support today and only tried to run the app manually. The workaround was like:
export LIBGL_ALWAYS_SOFTWARE=1
./myapp

I just install FluffyChat using FlatHub in my Byzantium backports environment (mesa 24.3.2) and can conclude that it works pretty well.
The side effect is I found dozens very nice apps written in flutter that I’d like to try

Thanks for your follow up @galilley
I should have mentioned that I’m on Mobian and perhaps assumed too early that it generally doesn’t work because of missing GLES 3.0 I didn’t dig deeper so far. Would you mind testing whether a binary compiled by me works for you flawlessly? 
If so, you could download the ARM build here: v0.13.0 - epinez/Energize - Codeberg.org

Looks like it works as expected…
Of course, gles3 is still not supported, but some of its critical parts are. So, Mesa version matter.

Thank you! 
That’s really nice to hear. I’ll have a look at what’s the problem on Mobian

Okay so here’s a quick follow up. tl;dr: export GDK_GL=gles needed.
Check mesa versions:
mobian@mobian:~/Downloads$ apt list --installed "mesa-*"
mesa-libgallium/testing,now 25.0.3-1 arm64 [installed,automatic]
mesa-va-drivers/testing,now 25.0.3-1 arm64 [installed,automatic]
mesa-vdpau-drivers/testing,now 25.0.3-1 arm64 [installed,automatic]
Try to run app directly:
mobian@mobian:~/Downloads$ ./energize/energize

Try to run fluffychat directly (build from Github):

Hmm, but why is the installed FluffyChat version via Flathub working?
mobian@mobian:~/Downloads$ grep Exec /var/lib/flatpak/exports/share/applications/im.fluffychat.Fluffychat.desktop
Exec=/usr/bin/flatpak run --branch=stable --arch=aarch64 --command=env --file-forwarding im.fluffychat.Fluffychat GDK_GL=gles fluffychat @@u %U @@
Ah, it’s setting the environment variable GDK_GL=gles…
Can also be found in their Flathub manifest.
Run app again with env:
mobian@mobian:~/Downloads$ env GDK_GL=gles bash -c ./energize/energize
Gdk-Message: 15:10:11.935: Unable to load from the cursor theme

While GLES 3.0 will just add power save on active-mode and not in inactive-mode and suspend-mode. We already have big issues on power save on inactive-mode and suspend-mode i hope it is bugs on software and not on hardware, if it is hadware-bug we need Librem 5 Fir Release to tackle this powersave erratas.
Librem 5 Still Wonderfull!

Thanks @austriancoder
THE REAL FUTURE FOR LIBREM 5 IT IS IN THE HANDS OF Christian Gmeiner. Otherwise the Librem 5 it would be a Museum Piece only.
