Looks like MTE is enabled by default on grapheneos for the pixel 8 - but earlier pixels do not have the required hardware for it.
Can it be disabled on an app-by-app basis?

Any idea how to test this, without having a pixel 8?

[SomberNight]

When exactly does the crash happen? Is it right at launch?

• Could you test with Electrum 4.5.0b1, which uses qt6 instead of qt5,
• and also with Electrum 4.3.4, which does not use qt at all?

(On the website, on the download page, click "Previous releases" at the top. There you can manually download apks.)

Can it be disabled on an app-by-app basis?

sure, but why would you?

[h2dden]

When exactly does the crash happen? Is it right at launch?

upon launch

[h2dden]

[h2dden]

could not install 4.3.4
says package is not valid

[SomberNight]

Thanks for testing.

• Is this with default settings on grapheneos, or did you change some settings regarding MTE?
  (on second reading of the FAQ item, I am unsure if it is enabled by default)

Looking at the traceback, it might help if we updated the python interpreter.

Can it be disabled on an app-by-app basis?

sure, but why would you?

To be able to use the application, as a workaround. This might not get fixed until someone who has hardware for it decides to contribute.

[h2dden]

memory tagging is enabled by default: haven't changed anything. there is not much to be changed apart from disabling on an app by app case
in the meanwhile, I am using the desktop/debian package: no time lost here

Looking at the traceback, it might help if we updated the python interpreter.

Python has some stability issues on android. Here are a few crash reports from the play store:

Just attempted to install and use Electrum 4.5.5 on GrapheneOS on the Pixel 8 and got a memory tagging error, too. I'm not knowledgeable enough to know if this helps, but I figured I'd provide some data where I can.

What are the odds this will get fixed? I'm nervous about using an app for money management that can't satisfy modern security standards

[SomberNight]

I now have a pixel running grapheneos that I can use to test, and I can reproduce some issues.

I tested with MTE enabled, on master, which uses python 3.10, (while 4.5.5 still uses py 3.8), and the app does NOT crash for me.
I think the python version bump might have fixed the segfault being reported by previous comments.

However, there are styling issues and the screen flashes white on certain interactions - though the app seems to function otherwise. Still, it looks really buggy. I think it might be Qt that is doing weird things. Maybe bumping from Qt 6.4 to higher could help.

Nevertheless, I don't have time to debug this further currently.

[SomberNight]

note: version 4.5.6 is now released, which has the behaviour I described above.

i.e. it should no longer crash but the UI behaves weird. Could someone else confirm this?
