That one is a bit more insiduous. It means the client ended up rendering
directly into the frontbuffer. Whilst any client has a bo as their frontbuffer,
or whilst a bo is on a scanout, it raises its active count, and while the
active count is non-zero it is not allowed to be given to a client to use as a
back buffer. The tracking is on the bo, so it should hold true as we
interchange the frontbuffer for TearFree. However, that screwed up somewhere
and has so far evaded all the asserts meant to try and catch the screw up much
earlier.

How big is the window being swapped in comparison to the multiple monitors? Do
it match the full screen size, a single monitor, or none?
