Game freezes after about 60 secs of gameplay

I am experiencing an issue with the game where the screen freezes after around 60 seconds of gameplay. The game runs normally at first, but after about a minute, the visuals freeze and no further action seems to be processed.
I have tested this on my ArchLinux

Do you encounter this issue with other games? Or only kungfu?

Yes. I encountered this issue with Mario and other games. It's strange because I can't easily debug it

I can not reproduce your issue on my Debian system. The game still runs well after 5 minutes. Most of the students use Ubuntu. But they do not report related issue.
