"can use", but does it use GPU acceleration? (taking into account provided GL version 2x)

When there used to be a weston-info I'm pretty sure it showed the gpu was being used.

Edit: about:support on firefox shows (albeit aarch64):

Please don't do that. See here:

libXcursor  is already a dependency for xorg, xvesa, xfbdev, flwm. gtk2, gtk3, ...
The cursors that depend on  libXcursor  are compiled into fltk even with  --disable-xcursor.
I saw no increase in extension size with  --enable-xcursor.

That's just the libraries. I wonder how much the apps compiled
against them grow.

--- End quote ---
Additional functionality is only relevant if it's actually useful and
someone is writing software that employs it.

It can be said surely by running btop:
if there's no additional CPU utilization after (for example) starting 3D-cube test rotation, then it runs on GPU.

It was about armhf with overlay supporting GL2 only. On aarch64 - idk (not tested), probably it works with distinct gpu and overlays (if it wasn't software GL4 or GLES path)

--disable-xcursor removed

In fact libfltk.so.1.4 is slightly smaller at 1,110,128 vs 1,110,224  :)
