Memory tagging error

[plus4c]

Since latest update yesterday am getting "Memory tagging detected an error in Blixt Wallet" on opening.

Hi, does it show any more information? What happens if you press on "More info" and "Show log"?

If I remember correctly you're using GrapheneOS?

This seems to be related to an ARM feature called MTE, which Go currently does not support properly, which is causing issues with CGO for our new lnd backend.

As suggested by someone using Mullvad VPN, it seems to be possible to disable MTE in GrapheneOS settings. Would you mind trying this?

Sadly, a proper fix would be needed inside Go itself, which is done yet.

@plus4c you can disable MTE for Blixt in app settings, @niteshbalusu11 tried this on GrapheneOS on a phone that has MTE hardware support.

A proper fix for this will as aforementioned need support in Go and CGO itself.

I am aware MTE can be disabled but thought it was better not to band-aid things. No other apps I have do this.
There was a change in GO and CGO since last Blixt update just a few days ago?
This error never occurred on last version.

Thank you.

We migrated to the new react native architecture and a more modern way of statically compiling LND which is faster and more efficient which uses CGO.

Yes, it's definitely better not to band-aid things. I'll try reproducing the issue to see if there is anything wrong on my side.
