TopDog's script to get the latest x11lib 1.6.12 fixes the problem! The X11 update must be done to address the issue in Wine 5.x and Codeweaver
I don't see any changes the relevant code in libX11 (e.g. _XCloseLC() still uses a global variable with no locks), and the relevant libX11 bugs are still open. Are you sure that the bug is fixed?
