MinT.6523

I have an issue that has only recently started happening - the screen is going black every 30 secs or so for about 2 secs then going back to game - I am not seeing the desktop during this though - is this the same issue reported in this thread (and supposedly fixed ?) )win 10. Had the problem before where it would drop to desktop for a few secs while map loading but that has now been replaced with the above. Making it very difficult to play - I have tried windowed mode but it makes no difference.
