Canvas (prev commit) made the big-track map self-recover but the Chromium compositor still hit 'tile memory limits exceeded' ~46x and 10k segments still janked. Three cheap levers: - tilecache: keepBuffer 2->1 and updateWhenZooming:false - fewer retained off-screen tiles in the compositor's raster budget on a high-DPI screen. - track/roads polylines: smoothFactor 2.5 (Douglas-Peucker in pixels) - a 10k-point track draws far fewer segments zoomed out, full detail zoomed in. - POI: cap markers by zoom (z>=16:500, 15:200, 14:80, 13:30) instead of a flat 500 - a handful near min-zoom, everything only when zoomed in close. |
