From 8361ed1f543a74c1d5fba1df4a2c5084f889a237 Mon Sep 17 00:00:00 2001 From: ocornut Date: Tue, 26 Oct 2021 19:23:04 +0200 Subject: [PATCH] Nav: wrap abs<>rel rectangle conversions before we attempt to switch the reference point from window->Pos to window->DC.CursorStartPos. This commit should have no effect. Current point makes rectangle invalid right after a scroll, for interactive actions it's rarely a problem but e.g. clipper will want to use g.NavID rect rel while scrolling.
