Motif assumes that you can call functions that lock the display inside XCheckIfEvent as it never calls XInitThreads itself. It also never uses threads.
It was never up to Motif to decide whether or not to call XInitThreads() - that decision was up to the applications, and if Motif assumed no application would ever do that, it was buggy and incompatible with such applications. https://gitlab.freedesktop.org/xorg/lib/libx11/-/merge_requests/150 is a proposed solution to the problem, but has not generated any interest in testing it or moving it forward, suggesting either everyone is building with the --disable-thread-safety-constructor option or is using correctly written software that does not make such assumptions. -- -Alan Coopersmith- alan.coopersm...@oracle.com Oracle Solaris Engineering - https://blogs.oracle.com/solaris
