[QUOTE="tourettes, post: 380780, member: 10858"] Not sure. Its just a "hack" to try to delay the texture unloading on C++ side (usually I won't touch the C# side code :)) fontEngine.dll is pretty stupid component (no logic inside it), it mainly exports some low level functions to C# side. So all the actual locking logic should go into C# side (I just added some safe guards as MP was sometimes panicing on my HTPC). Not sure if it has some side effects like rendering clitches etc. when MP side is not playing nicely. ...so, the C# should be handling the locking correctly and make sure that when the rendering pass is ongoing textures & surfaces are left alone in the fontEngine.dll side.
