Visualizing GC pause and thread running

[alexcwatt]

Thank you for this gem! I've recently started using it to analyze a system.

I'm curious about GC pause reporting. In the screenshot below, a particular thread is shown as running (not stalled) but some of the frames where it's shown as running are frames with a GC pause:

If I'm understanding correctly, the thread isn't actually running when there's a GC pause; I was wondering if there would be another way to represent this visually? The current definitions of thread stalled and suspended don't seem to fit the GC pause scenario, but maybe there is some way to make it more apparent that the thread is not running?

I could also be misunderstanding. Thank you for any insight you can add!
