For whatever is worth, I have tried switching my radeon to the EXA 
acceleration architecture. This indeed helps. most of the games:

The animations in kpat and kgoldrunner become fluid enough, and even kshisen 
becomes playable. The problem is that scrolling and general PC use gets more 
sluggish overall. So it's a compromise not everyone could agree to do.

I think kpat and kgoldrunner issues are minor, affecting only startup and 
accessory effects; but in kshisenso a long pause is added at each move, and 
this is a problem. Maybe it's easy enough to fix the rendering. of the board;

There was an environment variable to check the show the areas Qt updates when 
drawing a widget; who can remind it to me?
