Two-pass rendering was considered and rejected by the Egui developer. What they have is sort of one and a half pass rendering. Sometimes, things are wrong on the first draw, but correct on the next draw because info is retained from the previous frame.
Back in 2023, this created a bug where a text box was misaligned on alternate frames.[1] Amusingly, I tried to capture a video of this, and the 30 FPS video looked perfect, because it was capturing only alternate frames of 60 FPS refresh.

Bugs in layout can be very strange in Egui.
