Steps to reproduce

We are seeing some strange behavior especially on lower spec PCs where the flutter timer thread continues to wake up and fire for a long time after the app has been idle, sometimes it fires forever.

We are seeing 20-30% CPU usage while the app is idle, while we previously saw ~0%. The issue started somewhere between 1cfb17ff97635287d7ec689bc76e7fe4bb359a0a and a2d822d263d24a094d4bc37b5db920054a581232
