Description

After starting Android Studio on MacBook pro M1 (MacOS 15.7.3) with Flutter plugin installed the IDE feels reasonably responsive.

However, after launching the Flutter debug app target (I usually run the macOS target) and performing a few hot restarts, everything becomes sluggish and unresponsive, making the IDE nearly impossible to use.

I see there is a heavy CPU load even when there any apps running or no ongoing build processes in the IDE. Help / Diagnostic Tools / Activity Monitor...
