Hi all, I've recently made the switch to the snapshot xorg server and the related X libraries and I've discovered that my application stopped to works correctly!
Here the problem in short. I'm developing a multi-threaded application where the main thread run the X Window event loop. There is also a secondary thread that sometimes need to redraw the window or, more generally, perform operation on the X Display. In order to avoid problems I've arranged some locks so that the secondary thread perform its operations on the display only when the main thread is blocking in the XNextEvent operation. At this point is important to add that, yes, I'm using the XInitThread functions at the very beginning of the main loop. What happens is that the secondary thread blocks during the XSync operation until the main thread receive some events. I'm wondering if the assumption that I'm doing in my code is wrong or if it is a bug of the X server or may be the X library. It seems to me that it is like if Xlib does not honor the XInitThreads call because it does not allow an ordinary XSync to terminate if there is a pending XNextEevent call at the same time (by another thread). I hope someone can help me to clarify the problem.
