fix(linux): isolate AppImage GStreamer plugins to prevent ABI mismatch#444
Conversation
…plugins The AppImage bundles GStreamer from CI (Ubuntu 24.04, GStreamer 1.24). Previously, host plugin directories (/usr/lib/gstreamer-1.0/) were appended as fallback. This caused ABI version mismatches — host plugins compiled against a different GStreamer version fail with undefined symbol errors (gst_util_floor_log2, mpg123_open_handle64, etc.), leaving WebKit without usable codecs for YouTube playback. Since PR #434 installs the full GStreamer codec suite on CI, the AppImage is fully self-contained. Remove the host fallback and block host plugin scanning to prevent ABI conflicts across distro GStreamer versions.

CSS changes (main.css, settings-window.css): - Add @media (prefers-reduced-motion: reduce) — kills all 60+ infinite CSS animations for users who opt in, saves battery on low-end devices - Raise --text-faint #555→#777, --text-ghost koala73#444→#666 for WCAG-passing contrast on dark background (~3:1 from <2:1) - Remove max-height: 400px on mobile panels — content was silently clipped; panels now scroll internally with overflow-y: auto - Constrain .intel-findings-dropdown to min(380px, 92vw) on ≤480px screens — previously overflowed off right edge on narrow phones - Bump header height 40px→48px on mobile for comfortable touch target - Raise .variant-option, .findings-badge, .layer-toggle font-size from 9px to 11px on mobile for readability on high-DPI screens - Add min-height: 44px to settings tabs and runtime pills (WCAG 2.5.5) JS changes (CountersPanel, DeckGLMap, 4 data panels, badge): - CountersPanel: gate 60fps RAF loop via IntersectionObserver + document visibilitychange — loop pauses when panel is off-screen or tab hidden, resumes automatically; add matching cleanup in destroy() - DeckGLMap: replace 500ms setInterval news-pulse with a RAF loop that checks elapsed time (same 500ms cadence) — cooperates with browser frame scheduling, skips work when tab is hidden or render is paused - MacroSignalsPanel, StablecoinPanel, ETFFlowsPanel, ServiceStatusPanel: add !document.hidden && !this.element.classList.contains('hidden') guard so background-tab and off-screen panels skip their periodic fetches - IntelligenceGapBadge: skip 10s refresh when tab is hidden; clamp context menu coordinates to viewport bounds (prevents off-screen menu) https://claude.ai/code/session_01PgapzQLrB8RisivM6WvCz7

Summary
GST_PLUGIN_SYSTEM_PATH_1_0as safety netProblem
Users on various Linux distros reported GStreamer errors and no YouTube playback:
Root cause: The AppImage bundles GStreamer 1.24 from CI (Ubuntu 24.04), but the code appended host plugin directories as fallback. Host plugins compiled against a different GStreamer version (older or newer) fail with undefined symbol errors due to ABI mismatch. This left WebKit with zero usable codec plugins.
Why this is safe now
PR #434 added the full GStreamer codec suite (base, good, bad, ugly, libav, gl) to CI. With
bundleMediaFramework: true, the AppImage bundles all necessary plugins. No host fallback needed.Separate issue: Exec format error (aarch64 on x86_64)
One user also reported
Exec format errorwhen running an aarch64 AppImage — this is an architecture mismatch (wrong download), not a code bug.Test plan
