Debug Breakpoints don't work in Intellij Idea Community Edition (Windows 10)

[atsushieno]

I am hitting the same issue on Ubuntu 20.04. I have a repro screen recording: https://drive.google.com/file/d/1jbNdwQfTOZ5F0Qba6JKNDf9TCFkH4UHp/view?usp=sharing

I still see "some code" or "sometimes" IDEA stops at breakpoint as expected, but it's not predictable to me.

IntelliJ IDEA 2021.2 (Community Edition)

Runtime version: 11.0.11+9-b1504.13 amd64

Current Desktop: ubuntu:GNOME

Possible conditions I can think of:

• code file opens with some specific context (e.g. commonMain opens within desktop context while breakpoints are set on Android context) - if such a bug exists on MPP support plugin.
• some cmpiler plugin injection involves debuggee code that JDWP can normally handle, and it does not work at Window()'s immediate content on Desktop (which is what I particularly observe).
• It works only with certain JVM. I tried 14 and 16 as well, but I don't think I can reliably run the debuggee (app), IDEA and/or Gradle with certain version to verify - especially when Gradle deamon persists.

Same here, I am using the ultimate version of Inteliij on Ubuntu 20.04
