[PATCH 1/5] d3d9/tests: Add another flush to work around an intermittent test failure on fvwm2.

Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?

Full results can be found at:
