It appears we are painting more frames than are getting swapped:

xmir_dri2_copy_region
xmir_dri2_copy_region
xmir_dri2_copy_region
xmir_dri2_copy_region
xmir_dri2_copy_region
xmir_dri2_copy_region
xmir_dri2_copy_region
xmir_dri2_copy_region
xmir_repaint
xmir_swap

As opposed to a smooth rendering client:

xmir_dri2_copy_region
xmir_repaint
xmir_swap
xmir_dri2_copy_region
xmir_repaint
xmir_swap
xmir_dri2_copy_region
xmir_repaint
xmir_swap
