   This issue might be a duplicate of existing issues. Please check:

   • OpenCode desktop version black screen issue #15799: Similar macOS desktop black/white screen on restart
   • macOS Desktop: Session Diff causes permanent blank screen until storage/session_diff is deleted #15683: macOS Desktop blank screen (different trigger — Session Diff corruption — but similar symptom of sidecar healthy while UI is blank)

   If your issue is distinct from these (e.g., the WebKit crash in WebCore::SelectorChecker::attributeSelectorMatches is a specific root cause not covered there), please clarify the difference so maintainers can track it separately.
