1.11 Watch face data corruption #1376

Open danielrparks opened 2 years ago

danielrparks commented 2 years ago

Verification

[X] I searched for similar bug reports and found none was relevant.

What happened?

After playing with different watch faces, the Casio 7-segment font was corrupted

What should happen instead?

The font should continue to work no matter how I interact with the watch

Reproduction steps

Not sure if it will be possible to reproduce this one.

Installed the resource pack using itd
Tried all the different watch faces. They all worked.
Went back to PineTimeStyle and played with the colors for a while.
Waited several hours
Played with the watch faces again. The Casio font was corrupted.

More details?

This is a sealed watch, unfortunately, so I don't have swd access.

Version

v1.11.0

Companion app

Gadgetbridge 0.70.0, itd r199.1e072a3

I reset the watch and the face loaded correctly, so the corruption was in-memory and not in the files themselves.

@danielrparks Thanks for the report! This is something I've seen a few time during development. The cause was the the memory allocated to LVGL (the UI library that handles all the drawing and fonts) was full or fragmented, and LVGL couldn't allocate a buffer big enough to load the font into. Switching to another app then coming back to the watch face can potentially work around the issue. Resetting the watch is another work around.

The fix is not easy, though... I have a few options to optimize memory usage and reduce a bit of overhead in memory. This would allow to allocate more memory for the UI and hopefully reduce the chances of triggering this issue.

As mentioned in another comment of #1377 , I also see nothing in terms of visible external assets (like the photo in https://github.com/InfiniTimeOrg/InfiniTime/issues/1377#issuecomment-1287387076) on the casio watchface specifically when it wakes for chime every hour. That might be a separate issue because it seems to only happen during chime wakeup. Going to another app and back fixes it.
