I wonder could they've been related to GL 4.3 being enabled and games using
additional features, which got fixes after that...

The attached perf log shows slow (spilling) shader compilations just before
crash, so micro freezes could be due to shader compilation.

You could verify that by monitoring perf log while doing things in the game. 
If it gives messages about shader compilation right when you have momentary
freezes, that's the issue.  That will mainly be helped by shader cache.

As this was mainly about crashes, I wonder whether this could be closed as
fixed?
