piCore15.0 Beta
Juanito:
I tried updating xorg-server as this provides the modesetting driver, but no luck.
If I load graphics-KERNEL, but delete the modesetting driver, x starts using the llvmpipe software acceleration.
One thing I notice is that when graphics-KERNEL is loaded at the console prompt, the screen blanks and doesn't come back without turning it off/on - this doesn't happen with piCore64-15.x (v3d) and didn't happen with piCore-14.x (vc4).
So far no amount of googling turns up anything.

Hello, I have pi3b+ under hands that used to test gtk4 3d app, it works. For TC15 with v4 overlay `inxi -b` output there looks like

screen (LCD) doesn't blank and GTK apps with GL 4.5 CoreProfile work not so fast but acceptable taking into account hardware.
If there's need some info for comparing, let it know.

and with modesetting

Perhaps look at the script mention in the RaspiOS package
