The problem is, "Invisible parts of the screen" = the part that is zoomed to the upper part of the water, I'm not talking about the visible part that scrolls from right to left in the past. It is completely excluded from the calculation by the software. We can never control the top water in bottom zoom. While in zoom, the smallest foam in deep water, it takes a long time for the transducer to come out of the water, bounces on the screen and re-finds the bottom.
As a software developer, the past is doing screen refreshes for a very short time, maybe 1 second. This causes the screen to jump because of not receiving the smallest data for a short time. If the extension of this time looks at the last 5-10 seconds and refreshes the screen according to its average, it may prevent the screen jump. Maybe it's another problem, I just need to find a solution.
