@ -39,6 +39,9 @@ Breaking changes:
Other changes:
- Fixed cases where CTRL+Tab or Modal can occasionally lead to the creation of ImDrawCmd with
zero triangles, which would makes the render loop of some backends assert (e.g. Metal with
debugging, Allegro). (#4857, #5937)
- Inputs, Scrolling: better selection of scrolling window when hovering nested windows
and when backend/OS is emitting dual-axis wheeling inputs (typically touch pads on macOS).
We now select a primary axis based on recent events, and select a target window based on it.
