Once a popup's dim is up, the screen below is drawn once into an image (LV_USE_SNAPSHOT), darkened as the dim layer darkens it, and shown opaque over the screen with the dim layer cleared. LVGL then starts drawing from that image; an lv_image with no background never reports that it covers, so it answers the cover check itself. A full frame under a popup: 45.7 -> 32.6 ms; freezing costs ~29 ms once, as the popup settles. One popup at a time (a second one dims live), a strip keeps the status bar dimmed under top-layer popups, the image goes with its popup, and the popup dims live again if its screen goes first. POP_BOTTOM (over a live map) isn't frozen. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
