A common problem of immediate mode GUI is how to make the parent component's size dynamically determined by child component's content (2-phase dynamic layout). Does Egui solve this issue?
This mechanism can get you there most of the time.
That’s… eww. It probably doesn’t often cause real problems—though it surely could, as it’s allowing temporary rendering with out-of-bounds values that a developer might have expected to be clamped—but it’s still very eww, the idea that mutating data leads to parts of a frame being rendered with different data.
I agree, that shouldn’t happen and it might be a bug, because the input is handled after drawing the initial frame and should be clamped before starting to draw the next frame. Drag events are tricky though, because they come with a frame delay by default (you have to recognize the drag).
Does this reproduce reliably on desktop? If so then I can create an issue for this.
