+## Spöktecken i vissa terminaler vid fönsterflytt
+
+**Status:** öppen — behöver reproduktionsinfo från värdterminalen.
+
+**Symptom:** när ett fönster (t.ex. TUI-FM) dras runt kan enstaka ikoner
+och bokstäver "fastna" på skärmen — ofta från vänsterspalten i TUI-FM —
+tills en annan ruta dras över dem.
+
+**Analys hittills:**
+
+- Kompositorn är verifierat korrekt: headless-frames (daemon-läget) är
+  pixelperfekta efter godtyckliga drag — varje rad exakt rätt bredd,
+  inga dubbletter (`tests/integration.py` + manuella tmux-tester).
+- I tmux (strikt referensterminal) uppstår inga spöken, varken under
+  eller efter drag.
+- Rotorsaksklass: terminalen/fonten och `unicode-width` är oense om
+  glyfbredder (typiskt emoji med tvetydig East-Asian-Width, t.ex. ⭐ ➕),
+  eller terminalens hantering av delvis överskrivna breda glyfer.
+
+**Åtgärdade delar (som inte räckt fullt ut enligt rapport):**
+
+1. Full omritning vid drag-släpp/stängning/snap (`needs_full_redraw`).
+2. `SafeBackend`: explicit markörpositionering (`ESC[y;xH`) för varje
+   cell som skrivs — breddoenighet kan inte längre ackumuleras inom en
+   rad.
+3. Skade-expansion för breda glyfer: när ett brett tecken ersätts av
+   ett smalt skrivs högercellen över explicit (ratatui-diffen ser den
+   inte eftersom båda buffertarna har space där).
+
+**För att komma vidare behövs:**
+
+- Terminalemulator + version (Konsole? Kitty? Alacritty? ...) och font.
+- `echo $TERM` i terminalen där felet syns.
+- En PNG-skärmbild via TUI-WM:s inbyggda `alt+p` när spöket syns
+  (visar kompositorns bild) **plus** en riktig skärmdump av terminalen
+  (visar vad terminalen faktiskt ritar) — skiljer de sig är felet
+  bekräftat terminal-sidigt.
+- Test i en annan terminal (t.ex. kitty eller wezterm) för jämförelse.
+
+**Möjliga nästa steg:** rendera om hela raden (inte bara cellen) när en
+rad innehåller tecken med tvetydig bredd; alternativt heltäckande
+frame-omskrivning med synkroniserade uppdateringar (DEC 2026) som i
+klient-läget, där problemet inte kan uppstå.
