Finally I get around to trying git bisect :)
I started with Equalizer current HEAD (bad) and release-1.0.1 (good).
Git bisect tells me that 9ab87c0bac94d1962d21491b96cec9b7b3ad8c6c
makes the difference (log attached). Before this, I get > 70 FPS with
my current test video, after it I get only ~20 FPS.
But I must admit that I don't understand the impact of this commit and
why it causes the drop in frame rate. I only see this happen with Bino,
not with my other application. So maybe Bino does something wrong here?
