does anyone know how to enable DRI3 for xf86-video-modesetting?
it's on by default

But Xorg.0.log only mentions DRI2, see:
user@machine:/var/log$ grep DRI Xorg.0.log
[ 13.309] (II) glamor: EGL version 1.4 (DRI2):
[ 13.952] (II) modeset(0): [DRI2] Setup complete
[ 13.952] (II) modeset(0): [DRI2] DRI driver: i965
[ 13.952] (II) modeset(0): [DRI2] VDPAU driver: i965
[ 13.976] (II) GLX: Initialized DRI2 GL provider for screen 0
Why doesn't it say anything about DRI3? When enabling DRI3 in xf86-video-intel for example, Xorg.0.log lists DRI3, but with xf86-video-modesetting it does not (see above).
Try running this command from a bash prompt:
LIBGL_DEBUG=verbose glxinfo | grep -i libgl
Whether I use modesetting or intel with DRI3 enabled, I get:
libGL: Using DRI3 for screen 0
(BTW I was just as confused as you about why I didn't see DRI3 in the Xorg log before I found someone who quoted this command. I think that the modesetting driver just isn't programmed to print it out properly.)
While a cosmetic issue, it is very confusing indeed. Please keep this bug open. It needs fixing.
still happen in xorg drivers 1.19
