Mac OS X 10.1.x apparently has a thread safety bug in its version of AppKit. Unfortunately this results
in a frequent lock up when creating windows because they are not created in the main thread. The
following message is outputted to the console when this happens:
*** Assertion failure in popState(), NSViewHierarchyLock.m:512
Invalid parameter not satisfying: th->topOfStack >= 0
This makes the Xserver unusable on Mac OS X 10.1.x. A patch to work around this problem is attached.
Created attachment 159 [details] [review]
Patch to files in Xserver/hw/darwin/quartz/cr
Could you please apply this to the XORG-RELEASE-1 branch, please?
