For some reason, the ImGui::Image() call causes the strange effect of input to break.
It's clearly receiving input, but the UIs do not respond to it (except to an ALT+TAB).
Notably, everything still renders and otherwise behaves fine, such that on a subsequent frame where that call isn't active, input is responsive again.
Seems to specifically be caused its internal "ItemSize()" call:
