I need to retry my old experiment with adding another match between newly added float color format and and bc_rgba_float .. but r/n I just rebuild kernel because modesetting driver failed to work ( I posted my dri3 err to mesa bugzilla and Karol Herbst asked if bug surface on modesetting DDX vs nouveau DDX.
