The DRI2 SwapBuffers request requires drivers to defer the swap work until some point in the future. It's entirely possible for the client that requested the swap to go away before that trigger occurs, resulting in DRI2 buffers being freed in DRI2DrawableGone and then the swap event crashing the server trying to access the freed buffers.
The relevant (fixed) crasher bugs are Intel: https://bugs.freedesktop.org/show_bug.cgi?id=28080 Radeon: http://bugs.freedesktop.org/show_bug.cgi?id=29065 I haven't tested nouveau's new pageflipping support, but it looks like it suffers the same problem. Since the big three drivers all suffer this problem, and all need to solve it in the same way, it might as well be done in DRI2 itself. _______________________________________________ [email protected]: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
