I need a few more details on the nature of the rendering issue and
driver versions.
The idea is to skip the flush in case we have nothing to flush (this is
required to avoid the too-early-flush during initialisation of the ring
buffer). Finding the circumstances of the flush that causes the issue
should help determine the root cause of the bug.
