This growth is bounded but is bad in some (not really rare) cases.
Estimates are up to 200GB for 4k screens.
Reproducible test case:
user resizing viewport with mouse, each frame being 1 pixel bigger.
going from half res->full res would have around 2000 heaps created, with up to 100mb per frame extra mem. only one of these is used at any given time
