Package: python-pygame Version: 1.7.1release-4.2 Severity: normal
I'm writing an application which needs to be able to switch between full-screen and windowed operation, which it does by deleting its old surface then creating a new one with pygame.display.set_mode(). At this point it often crashes in the set_mode() call, feezing my application until I send it a KILL signal. The new surface/window does appear on screen but stays black. The bug may be in SDL or even xorg or nvidia-glx, but I'm reporting it here because there is some python-specific info in the backtrace which I got by running with SDL_DEBUG=1. There is sometimes a delay before the backtrace appears. Locking assertion failure.
