…10434) ### Related * #10406 * emilk/egui#7276 ### What Show an orange dot to warn about multi-pass layout in egui. If it is shown, it means something called `egui::Context::request_discard` the previous pass, causing a multi-pass layout frame in egui. This is used to cover up some visual glitches, but it is also a bit costly and we shouldn't do it too often. An infrequent blinking of the dot (e.g. when opening a new panel) is expected, but it should not be sustained.  In this example the selection panel (outside the frame) shows a `ListItem` scope for the first time, which results in a single multi-pass frame.
