Sometimes multiple display lists are sent before a frame is generated.

When running the MotionMark 'Multiply' test with WR, I see the following if I log out each SetDisplayList and GenerateFrame message that the render backend receives:

SetDisplayList PipelineId(1, 2) Epoch(812)
GenerateFrame
SetDisplayList PipelineId(1, 2) Epoch(813)
GenerateFrame
SetDisplayList PipelineId(1, 2) Epoch(814)
GenerateFrame
SetDisplayList PipelineId(1, 2) Epoch(815)
SetDisplayList PipelineId(1, 2) Epoch(816)
GenerateFrame
SetDisplayList PipelineId(1, 2) Epoch(817)
GenerateFrame
SetDisplayList PipelineId(1, 2) Epoch(818)
GenerateFrame
SetDisplayList PipelineId(1, 2) Epoch(819)
GenerateFrame
SetDisplayList PipelineId(1, 2) Epoch(820)
GenerateFrame
SetDisplayList PipelineId(1, 2) Epoch(821)
SetDisplayList PipelineId(1, 2) Epoch(822)
GenerateFrame
SetDisplayList PipelineId(1, 2) Epoch(823)
GenerateFrame
SetDisplayList PipelineId(1, 2) Epoch(824)

Every now and then, two display lists are sent in between a GenerateFrame.

I'm not sure if this is actually a bug - maybe it's expected? But I'm wondering if it might be related to sometimes seeing varying framerates in some of the MotionMark tests.
