I found in changelog this:
https://docs.mesa3d.org/relnotes/24.3.0.html
Adam Jackson (8):
meson: Introduce the legacy-x11 option
glx: Move DRI2 client support behind legacy-x11
egl/x11: Move DRI2 client support behind legacy-x11
gallium/video: Move DRI2 support behind legacy-x11
...
Seems, the new Mesa compiled without option 'legacy-x11' - since ver
24.3.0 Mesa don't depend on libxcb-dri2-0.
