Package: libgl1-mesa-glx Version: 6.5.1-0.1 Tags: patch AllocAndFetchScreenConfigs always calls UnlockDisplay twice without an intervening LockDisplay. We found this because Xlib/XCB asserts that you can't unlock the display if you don't have it locked.
While fixing this we noticed that SyncHandle isn't consistently called after UnlockDisplay in this function. --- glxext.c 26 Sep 2006 23:56:20 -0000 1.25 +++ glxext.c 6 Oct 2006 00:17:39 -0000 @@ -1016,11 +1016,11 @@ static Bool AllocAndFetchScreenConfigs(D if (!_XReply(dpy, (xReply*) &reply, 0, False)) { /* Something is busted.
