It would be really helpful if there was a way to restrict MOZ_DUMP_PAINT to just a single content window's document tree. The performance of logging the entire browser is bad, and the amount of noise in the log output makes it hard to extract relevant information. (Maybe there's a trick that I'm missing/overlooking.)
I usually use the pref layout.display-list.dump-content which only affects content processes.
