I was curious, so I took a peek at my app on Windows. It’s a pretty useless data point, but this does not occur with a 2022r2 build on Windows 11 running in Dark Mode using non-Desktop-prefixed TextArea.
The specific view structure is Window > PagePanel > ContainerControl > PagePanel > ContainerControl > PagePanel > TextArea.
I do not know what the key factor is, but I do not see the problem with my toolchain.
I tried to reproduce it with the following scenarios in 2024R2.1 on Windows 11 (latest), and was unable:
- DesktopTextArea > DesktopWindow
- DesktopTextArea > DesktopContainer > DesktopWindow
- DesktopTextArea > DesktopContainer > DesktopContainer > DesktopWindow
- DesktopTextArea > DesktopContainer > DesktopContainer > DesktopTabPanel > DesktopWindow
- DesktopTextArea > DesktopContainer > DesktopTabPanel > DesktopContainer > DesktopTabPanel > DesktopWindow
I’m also believing the reports of a random behavior that I couldn’t see by myself in new projects. Maybe the OP triggered a specific Xojo bug needing specific legacy code breaking internal functionalities on the upgrades? I’ve saw those kind of things in the past.
