Unfortunately, computing topographic curves from rasterized elevation data is horribly expensive mathematically, and YAAC always does that on-the-fly based on the current zoom level and map center (rather than sucking up disk space saving rendered tiles for a particular tile and zoom). Not knowing how uneven the terrain is in your vicinity, all I can suggest is to adjust the topographic line spacing to be further apart, so fewer curves have to be computed. You will find it more efficient to use topographic regions, where the map background is colored based on the elevation at each pixel (which therefore doesn't have to figure out which way a topographic line is bending in each pixel).

Okay, i still have no idea how I managed to trash my tiles. I did manage to download them and gain some normalcy.
My newest issue is either just me as the user having an issue or possibly the pi, I dont know. anyways it seems to tak a considerable amount of time (more then 30 minutes) to get the topo layers lines and colors to show.
I am using a pi 4 4GB RAM with Bullseye, and for the most part nothing ls operational on here yet. I was in procss of settingn up things whn I encountered this.
