Minimal, Complete and Verifiable Example code:

ImGui::SetNextItemWidth(-FLT_MIN);
static int test_type = 0;
ImGui::Combo("Test type", &test_type,
    "Single call to TextUnformatted()\0"
    "Multiple calls to Text(), clipped\0"
    "Multiple calls to Text(), not clipped (slow)\0");

The label width (and item spacing between the combo and the label) gets added to the item's total width, which then keeps pushing the window's content size.

Disable the label to prevent the window from growing forever:

ImGui::Combo("##unique_id_here", ...);
