ChatScreen::refresh() loads + renders MESSAGES_PER_PAGE messages while the LVGL mutex is held (the open path runs on the LVGL task's lv_task_handler). On a 32+ message conversation with a memory-pressured heap, 20 LittleFS reads + parses exceeded LVGLLock's 5s timeout and asserted (crash). Cap to 10 so the under-lock work stays well under budget; older messages load on scroll. This is a mitigation. The real fix is to do the message I/O off the LVGL lock (load lock-free on the main loop, render under the lock) so a large conversation neither freezes the UI nor risks the timeout.

Pyxis
An LXMF and LXST client firmware for T-Deck, built on a highly modified fork of microReticulum
Very much WIP, don't expect stability :)
Features
Reticulum transport over:
- RNode-compatible LoRa
- AutoInterface (local wifi)
- TCP Client
- BLE Interface (barely working if at all)
Other features:
- GPS-synced time
- One really annoying beep when you get a new message (user toggle)
- View the announce stream
- Choose a propagation node (and sync with it) (fixed in v0.2.1)
- Set auto announce timer
- Light up keyboard (user toggle)
Will crash in about 5 minutes of normal use (sorry)I had 5d uptime on v0.2.0 with BLE disabled- Make LXST voice calls (codec2 only, quality sounds horrible coming out the other end in Columba, needs work)
Why "Pyxis"
Pyxis, latin for "compass," is a constellation in the southern sky depicting a mariner's compass. Small but essential, the compass ensures every message finds its destination - even when the path is uncertain.
