Details

I got this request at least twice. Markus told me he has an idea that could help in at least some of the cases, so filing a bug to have a place to discuss this.

Flags: needinfo?(mstange)

We capture "cause" stacks for Styles and Reflow markers. But we currently do not capture stacks when nsRefreshDriver::ScheduleViewManagerFlush() is called, which happens whenever we know that there's something to paint. We could start doing that, and expose it as the cause of the display list marker for the paint.
