Opening Popover Causes Noticeable Slowdown
In testing GTK4 I've found that opening a popover - any popover - causes a large amount of slowdown afterward. Using the FPS overlay I noticed when I start an app, fps roughly matches refresh rate (e.g. 144hz - 144fps) for everything. After opening a popover, anything animated - e.g. scrolling, transitions - causes a large and noticeable dip (~60fps). This makes apps feel very sluggish after opening a popover.
