On a wide panel Vegas mode spent much of its time showing black. At 50px/s on a 512px display, one display width of blank is 10.2 seconds, which makes several long-standing behaviours expensive: - ScrollHelper prepended a full display width of black as an "initial gap", charged once per cycle — 10.2s of black at the start of every rotation. - Plugins without get_vegas_content() are captured off a full-display canvas, so their blank margins entered the ticker too. Measured: of-the-day drew 35px of "No Data" on a 512px canvas (92% blank), youtube-stats 142px of content with 185px of black either side. Only the scroll_helper path had any trimming. - Cycle transitions deliberately pushed a blank frame and then recomposed synchronously: 84ms at best, 4.8s at worst, every millisecond of it black. - buffer_ahead doubled as the cycle size, so a 21-plugin install showed 3 plugins per cycle and took ~7 cycles to come around. - separator_width was applied between every image rather than at plugin boundaries, so a per-row ticker like the F1 scoreboard (116 images, which it renders 4px apart internally) got a 32px chasm between each row — and the width budget didn't count those gaps, so the plugin quietly occupied far more of the panel than intended. Changes: - src/vegas_mode/geometry.py: numpy column-ink primitives shared by the trimmer and the audit tool, so the number reported is the number acted on. A Python per-column loop over a 17,000px strip is far too slow for the render path. - PluginAdapter trims every content path, not just scroll_helper. Only outer edges are cropped: interior blank columns are the plugin's own layout (logo left, score right) and closing them would corrupt the design. A plugin on a non-black background is inherently unaffected. - ScrollHelper.create_scrolling_image takes an explicit lead_gap, still defaulting to display_width so the many standalone-ticker callers are unchanged. Vegas passes lead_in_width (default 0). - Cycle end holds the last rendered frame instead of blanking, turning the recompose into a brief freeze rather than the panel switching off. - plugins_per_cycle (default 6) is split from buffer_ahead, which goes back to being only a prefetch low-water mark. - max_plugin_width_ratio (default 3x display width) caps one plugin's share of a cycle. Overflow is deferred, not discarded: a rotation offset advances each fetch so later rows appear on subsequent cycles. Single oversized images are cropped at a blank column so the cut misses glyphs. - Composition groups images by plugin: rows are joined by intra_plugin_gap (default 8) and separator_width applies only between plugins. The width budget now counts those gaps. - Plugin data updates no longer run on the Vegas render path. All new settings are user-configurable in Display -> Vegas Scroll, including min/max cycle duration and dynamic duration, which previously existed in code but were reachable only by hand-editing config.json. Measured with scripts/dev/vegas_audit.py on a 512x64 panel: mean ink coverage 42.7% -> 69.4% fully blank 5.9% -> 0% reads as empty 13.6% -> 0% worst blank stretch 4.8s -> 0s full rotation 414s -> 123s plugins per cycle 3 -> 6 Note the metric choice: a "fully blank" scan (>=95% black viewport) reported only 0.4% and badly understated the problem, because two full-width segments with mid-canvas content never fully blank the viewport — they hold it at ~28%. window_coverage_stats grades every viewport position by how much ink it carries, which is what tracks perceived dead time. Known remaining: cycle transitions still freeze ~3.5s while the next cycle is fetched. Fixing that needs background prefetch, which is deferred because the fallback-capture path mutates the shared display_manager.image and racing it against the render loop risks torn frames.
