I've got a strange behavior with OpenGL: - an app A, tries to load another app B - on B startup, in x11drv init, the OpenGL initialization goes havoc: after the dl_open is made, fs:teb gets corrupted (ie gets changed) the point where this change is made varies over time (I assume, the OpenGL lib creates a thread, and depending on thread sync, it happens at various points) - more interesting, the second time one tries to launch B from A, it succeeds (in that case the corruption doesn't occur) those "features" didn't appear before Alexandre latest fd changes to the server, but I don't think that's a bug in there. It looks more like a timing/sync issue that the latest changes uncovered, but it likely existed before and where less prone to happen my OpenGL libs are from nvidia. Does anyone know what libGL does behind our back ? is there we can do against it ? A+ -- Eric Pouech
