--- Comment #9 from Matthew Waters (ystreet00) <ystreet00 at gmail.com> ---
This seems to have been solved in the transition to glbasememory.

gst_gl_base_memory_alloc_data() (which controls the sysmem allocation) is only
called when necessary from the memcpy implementation or from the cpu accesses
of the dependant classes.

    gl: add a base memory object

    It handles the following
    - GstAllocationParams -> gst_memory_init transformation
    - Makes sure that map/unmap/create/destroy happen on the GL thread with
      a GL context current.
    - Holds a possible sysmem accessible data pointer with alignment.
    - Holds the need upload/download transfer state
