DisclosureTriangle.DrawInto Method is broken on all platforms since Xojo 2018.2. This appears at the Microsoft Example. The Bug was fixed in Xojo 2018.3.
When using StackView with Xojo 2017.2 on Linux think about the bug „49401 - Linux: some controls are not placed correctly when on a non-Transparent ContainerControl“. This was fixed for the most controls in Xojo 2017.2.1. In Xojo 2018.1 it was fixed for Feedback case 50767 and 50870.
Currently there seems to be a bug in the Listbox under Linux (GTK+3) in Xojo. The Listbox header is displayed normally within the ContainerControl, but not the content area of the Listbox. To see the bug, unfold all tabs of the Apple demo and scroll down. The Listbox shines through outside the ContainerControl. ↠ Feedback case 49401.
Microsoft Windows Support only for builts with Xojo Version >= 2018.1.
