Im playing with simple OpenGL shader example (compiler is Mingw) - whole thing worked fine on win7 but since i "upgraded" to win10 Home QtCreator sometimes freezes the moment i hit debug button. It happens about once per 5 tries. Whats strange once QtCreator is frozen other aplications start to act strangely - they have problems refreshing windows, web browser cannot access net and after a few seconds everything freezes. Even ctrl-alt-del does not work - all i can do is press "reset" button. Any suggestions?
