FYI, when I use decompose 1.0.0, it's fine, but with 2.0.0-beta-01, I have a crash with distributable release build (fine in release build), it seems to only occur after a transition from one screen to the other.

SwingMainThreadChecker not found

`2.0.0-beta-01`:
• ./gradlew :dlvr-editor:runReleaseDistributable 💥
• ./gradlew :dlvr-editor:runRelease ✅
`1.0.0`:
• ./gradlew :dlvr-editor:runReleaseDistributable ✅
• ./gradlew :dlvr-editor:runRelease ✅

I'm running it on desktop without compose multiplatform, simple Jetbrains compose for desktop

[Arkadii Ivanov]

Do you have a full stack trace?

[Olivier Patry]

Sorry I missed the answer.
I'll check that when I go back to work on Monday.

[Arkadii Ivanov]

It appears that ProGuard removes SwingMainThreadChecker, the same issue usually happens with SwingDispatcherFactory. Try adding the following rule to your ProGuard config file:

-keep class com.arkivanov.decompose.extensions.compose.jetbrains.mainthread.SwingMainThreadChecker

[Arkadii Ivanov]

I have added this information to the docs.

[Olivier Patry]

I do not use ProGuard (AFAIK)

I believe ProGuard is used by default. https://github.com/JetBrains/compose-multiplatform/tree/master/tutorials/Native_distributions_and_local_execution#minification--obfuscation

Could you please try the fix I mentioned above and check if it helps?

[Olivier Patry]

Monday morning… need some ☕ coffee apparently 😅

So, good news, you were right, ProGuard issue and fixed by your suggestion, all good 👍

[Olivier Patry]

thanks for the support 🙇

[Arkadii Ivanov]

You are welcome! And thanks for reporting the issue.
