Instead of disabling DMABuf for all users (hurting AMD/Intel/X11
performance), detect NVIDIA GPU + Wayland session at startup and
only apply WEBKIT_DISABLE_DMABUF_RENDERER=1 for that combo.
Detection checks /proc/driver/nvidia/version first (fast, no
subprocess), falls back to scanning /proc/modules for nvidia.
GPU policy remains Always for everyone — the DMABuf workaround
only affects buffer sharing between WebKitGTK and the display
server, not GPU-accelerated CSS/layout/paint.
Root causes addressed:
- track-list had no _itemSize hint for flow layout — virtualizer
defaulted to 100px, measured actual ~33px rows, then called
_correctScrollError/scrollTo on every scroll causing visible jumps
- will-change:transform on virtualizer elements caused nested GPU
layers (virtualizer positions children with transforms internally)
adding compositor overhead instead of helping
- content-visibility:auto on album cards conflicted with virtualizer's
own DOM recycling, causing redundant layout recalculation
- track-list visibilityChanged handler wrote to store synchronously
on every event (per-item during scroll) without any throttling
- IIFE closure in renderTrackRow created a new function per row per render
Fixes applied:
- Add _itemSize:{height:33} + fixed height:33px on .track-row (matches
queue-panel pattern that already worked smoothly)
- Add overflow-anchor:none on track-list virtualizer
- Remove will-change:transform from all 6 scroll containers
- Remove content-visibility:auto from album cards
- RAF-throttle visibilityChanged scroll position saves
- Replace IIFE with direct cols.map() in template
contain:strict includes size containment which caused a timing issue
where the flex-based main-panel height wasn't resolved before the
virtualizer measured its container, resulting in track-list rendering
at ~20% height on first load until something triggered a relayout.

- content-visibility: auto + contain-intrinsic-size on .album-card for off-screen skip
- cover-grid, track-list, queue-panel, artists-view, genres-view, playlist-view
- Primary views (tracks, albums, artists, genres, playlists, settings) created once and kept in DOM
- Navigation toggles display:none/display:'' instead of destroying/recreating components
- viewCache Map bounded to 6 entries — no memory leaks
- Detail views (artist-details, playlist-details, genre-details) remain ephemeral
- Scroll positions naturally preserved by keeping DOM alive
- No virtualizer reinit, no data refetch, no image reload on navigation
- contain: layout style on .content-area to isolate main+queue from header/sidebar
- contain: strict on .main-panel for maximum layout isolation
- contain: layout style paint on .main-panel > * for paint containment per view
- contain: layout style paint on sidebar to isolate from main panel
- contain: layout style on .bottom-bar to isolate footer from content reflows
Sections start collapsed showing only heading, description, and a
chevron icon. Click to expand and reveal the fields. The open property
allows sections to start expanded if needed.
Progress bar now renders below the library row being scanned, with
a small status label (phase + percent) after the library name. Removed
the separate status-bar progress display.
Add Library now sits in the same row as Scan and Full Rescan, sharing
the same btn-primary style and size. Removed the standalone button
below the library list.
Scan and Full Rescan buttons now sit above the library list for easier
access. Libraries start unchecked — both buttons are disabled until at
least one library is selected.
Go's error interface has no exported fields, so json.Marshal produced
{} for the error message. Converting to string at the addWarning call
site preserves the actual error text in the JSON payload.
Contentless FTS5 cannot delete individual rows, but stale entries are
filtered out by the JOIN against track_metadata in search queries.
The index is rebuilt on the next full rescan. Removes ~10s of overhead
for a 25K-track library removal.
artist_credit_artist.credit_id references artist_credit.id, so the
child table must be cleaned before the parent. Same FK ordering fix
as the earlier recording_genres/recordings swap.
getLibraryRoot() returned "" after DirectoryPath was removed from
config.toml during multi-library migration. M3U8 relative paths could
not be resolved to absolute paths, causing every playlist track to
appear as phantom. Now falls back to the first library path from the
database when the legacy config field is empty.
Tracks from the pre-multi-library schema have library_id=0 and aren't
counted by CountAudioFilesByLibrary, causing a permanent count mismatch
that triggers a full scan on every launch. SoftScanAllLibraries now
claims matching orphans before comparing counts.
SoftScanAllLibraries compares audio file count on disk vs DB track count
per library. Unchanged libraries are silently skipped (no progress bar,
no events). Only libraries where files were added or removed since the
last scan get queued for a full scan.
recording_genres and release_group_recordings reference recordings.id,
so they must be deleted BEFORE the recordings table is cleaned.
Also extends toast duration to 8s for readability.
RemoveLibrary now polls until the cancelled scan goroutine finishes
before proceeding with the removal transaction. Also show removal
errors as toast messages instead of only logging to console, and
explicitly reload library list after successful removal.
Tracks from pre-multi-library schema have library_id=0 (default).
When AddLibrary creates a new library row, UPDATE orphaned tracks
whose file_path falls under the library's directory to use the new
library_id. This prevents the scan from hitting UNIQUE constraints
on every file and ensures track counts are correct immediately.
- Add checkboxes to library list with select-all header
- Soft Scan operates on selected libraries (queues each individually)
- Full Rescan stays global (nukes all data, rescans all libraries)
- Remove redundant 'Scan All Libraries' button
- Fix FullRescan Go backend to scan all libraries after wipe, not just first
Files that fail to save (e.g. UNIQUE constraint from pre-existing
tracks with a different library_id) were not counted in any progress
counter, leaving the progress bar stuck at 0%. Now increments skipped
so processed = added + skipped + updated reflects all files visited.
Scan() wrapper was deleted in Phase 11 but config-page.ts and
library-manager.ts still imported it. Use ScanAllLibraries() for
soft scan since multi-library model scans all libraries.
- Remove 'libraries' from View type union in app-sidebar.ts
- Remove Libraries nav item from sidebar navigation list
- Remove case 'libraries' view routing in index.ts
- Remove library-manager component import from index.ts
- Add CompactAfterLibraryRemoval on Queue: reloads surviving tracks from DB, resets currentIndex, unloads player if current track was removed, clears shuffle order
- Wire RemovalHooks in app.go OnStartup: StopPlayback → player.UnloadTrack, CompactQueue → queue.CompactAfterLibraryRemoval
- All existing tests pass with no regressions
