Placement and moving of the scenery elements such as taxipoints and projected meshes causes huge constant spike in CPU and GPU usage (up to 500 ms -100ms/frame respectively) and FPS drops to single-digits, as low as 2 fps and the image of the moved projected mesh disappears until I release the LMB. On the screenshot I am moving a big projected mesh covering the whole apron and runway. This worked ok in SU11. The issue persists in 220.127.116.11. Link to the project is included in private.
