500ms delay between drop part action and the actual refresh

When a part is dropped on the surface, there is about 500ms delay between the UI locks:

It adds a jitter when the actions are being done immediately on the part drop.

Was this ever fixed or figured out? I experience this as well and only after watching a video did I realize that it's not supposed to do that.

If it helps, I did find out the lag increases with the amount of crafts saved in the VAB/SPH, and only seems to occur when "Set pointer mode to: Nothing" (in KSP.log)
