I upgraded to 9/04 and tried again. There is an additional twist that has to do with bug 373634.
When I don't have the virtual desktop size set (meaning I have DRI HW acceleration) the bug still happens. When I do have virtual desktop size (meaning Mesa SW fallback) the bug does not happen. So this probably has something to do with DRI and/or desktop compositing. I use a bog standard x86 Ubuntu install. Basic kernel, basic X server settings, basic everything, really. -- Simple 50 line program hard crashes system https://bugs.launchpad.net/bugs/312708 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
