Thanks

Thanks for the report.

This crash seems to be cause by the Oxygen widget style, not by KPat itself, so I'm reassigning to the "Oxygen" component.

Can't reproduce here. (I could finish several rounds of several kpath games without crash). 

But again, this is something in QWidget::render, as other recent oxygen bugs. 

What's worrysome is that the last crash occurs in NVIDIA code (and I run with intel graphics card soo ...)

I have seen various crashes were the nVidia blob was present, and they were all a problem with the driver.. AFAIK QtGui doesn't call this driver stuff, so it is just a broken thing.
- Have you tried to update your nVidia drivers ?
Thanks
