Sorry for the long silence, I cannot reproduce the hang on exit with F-12 (tried on various machines). So for this part this bug is: "Closed Current Release" Please re-open if you still see this after updating to F-12. As for the cpu usage during the game, unfortunately many games are programmed with busy loops causing them to chew up 100% cpu, although I agree this is less then ideal, I'm afraid I don't have the time to go and fix this. So for this part this bug is: "Closed wontfix". |
Description of problem: Essentially, after closing the main window, the openlierox process busy loops and sits using 100% CPU time, instead of exiting. Version-Release number of selected component (if applicable): openlierox-0.57-0.13.beta8.fc11.x86_64 How reproducible: Always. Steps to Reproduce: 1. Run a local game 2. Play for a few seconds 3. Quit the game. What the process with top Actual results: The process doesn't exit properly and busy loops. Expected results: The game should exit correctly and not chew up CPU time. Additional info: During the game, even in local play you can see the following when running strace, which also causes the CPU to sit at 100%, despite the game not doing anything obvious: select(4,
