fix(linux): render UI correctly in AppImage (CSP nonce + SVG sizing)#4
Merged
Conversation
The Linux AppImage launched but rendered only a giant logo with no
layout. Root cause: Tauri injects a per-load 'nonce-...' into the CSP
style-src at runtime. Per the CSP spec, a nonce in style-src makes the
browser ignore 'unsafe-inline', so Angular's runtime-injected component
<style> tags (which carry no nonce) were all blocked by WebKitGTK. With
no component CSS, .brand-logo { width: 42px } never applied and the
<img> fell back to the SVG's 320mm (~1210px) intrinsic size.
- tauri.conf.json: dangerousDisableAssetCspModification ["style-src"]
so Tauri leaves style-src verbatim (keeps 'unsafe-inline', no nonce)
while still nonce-protecting script-src.
- tauri.svg: 320mm -> 320 intrinsic size (defense in depth).
- Also bundles GStreamer media framework + build deps for the webview
(fixes the earlier appsink error) and bumps version to 0.1.3.
Verified: rebuilt AppImage now renders the full UI correctly.

Problem
The Linux AppImage launched but rendered only a giant logo with no layout — the long-standing Linux render bug.
Root cause
Not a WebKitGTK/Wayland/Intel issue (ruled out — dev and prod bundles both render fine in the same engine). The real cause:
'nonce-…'into the CSPstyle-srcat runtime (__TAURI_STYLE_NONCE__).style-srcmakes the browser ignore'unsafe-inline'.createElement("style")— those<style>tags carry no nonce, so WebKitGTK blocked all component CSS..brand-logo { width: 42px }never applied and the<img>fell back to the SVG's320mm(~1210px) intrinsic size → giant logo, no layout.Fix
tauri.conf.json:dangerousDisableAssetCspModification: ["style-src"]— Tauri leavesstyle-srcverbatim (keeps'unsafe-inline', no nonce) while still nonce-protectingscript-src.tauri.svg:320mm→320intrinsic size (defense in depth, so the logo can never balloon again).appsinkerror) and bumps version to 0.1.3.Verification
Rebuilt the AppImage with the real CSP applied and launched it — the full UI now renders correctly (proper-size logo, header, Folders/Details panels, breadcrumb).
